A fatal flaw is reflected in failing to meet combinations of criteria that may be related in indicating the presence of bias order 400 mg viagra plus visa. An example would be inadequate procedures for allocation concealment combined with important differences in prognostic factors at baseline discount viagra plus 400mg fast delivery. Studies that meet all criteria were rated good quality; the remainder were rated fair quality. As the fair-quality category was broad, studies with this rating varied in their strengths and weaknesses: The results of some fair-quality studies were likely to be valid, while others were only possibly valid. A poor-quality trial was not valid; the results were at least as likely to reflect flaws in the study design as a true difference between the compared drugs. Criteria for assessing applicability (external validity) are also listed, although they were not used to determine study quality. Does the systematic review report a clear review question and clearly state inclusion and exclusion criteria for primary studies? A good-quality review focuses on a well-defined question or set of questions, which ideally refer to the inclusion/exclusion criteria by which decisions are made about whether to include or exclude primary studies. These criteria would relate to the four components of study design, indications (patient populations), interventions (drugs), and outcomes of interest. A good-quality review also includes details about the process of decision-making, that is, how many reviewers were involved, whether the studies were examined independently, and how disagreements between reviewers were resolved. Is there evidence of a substantial effort to find all relevant research? If details of electronic database searches and other identification strategies are given, the answer to this question usually is yes. Ideally, search terms, date restrictions, and language restrictions are presented. In addition, descriptions of hand-searches, attempts to identify unpublished material, and any contact with authors, industry, or research institutes should be provided. The appropriateness of the database(s) searched by the authors should also be considered. For example, if only MEDLINE is searched for a systematic review about health education, then it is unlikely that all relevant studies will be located. Is the validity of included studies adequately assessed? If the review systematically assesses the quality of primary studies, it should include an explanation of the basis for determining quality (for example, method of randomization, whether outcome assessment was blinded, whether analysis was on an intention-to-treat basis) and the process by which assessment is carried out (that is, how many reviewers are involved, whether the assessment is independent, and how discrepancies between reviewers are resolved). Authors Antiepileptic drugs Page 88 of 117 Final Report Update 2 Drug Effectiveness Review Project may have used either a published checklist or scale or one that they designed specifically for their review. Is sufficient detail of the individual studies presented? If a paper includes a table giving information on the design and results of individual studies or includes a narrative description of the studies, this criterion is usually fulfilled. If relevant, the tables or text should include information on study design, sample size for each study group, patient characteristics, interventions, settings, outcome measures, follow-up, drop-out rate (withdrawals), effectiveness results, and adverse events. The authors should attempt to synthesize the results from individual studies. In all cases, there should be a narrative summary of results, which may or may not be accompanied by a quantitative summary (meta-analysis). For reviews that use a meta-analysis, heterogeneity between studies should be assessed using statistical techniques. If heterogeneity is present, the possible reasons (including chance) should be investigated. In addition, the individual evaluations should be weighted in some way (for example, according to sample size or according to inverse of the variance) so that studies that are thought to provide the most reliable data have greater impact on the summary statistic. Controlled Trials Assessment of Internal Validity 1. Was the assignment to the treatment groups really random? Adequate approaches to sequence generation: Computer-generated random numbers Random numbers tables Inferior approaches to sequence generation: Use of alternation, case record number, birth date, or day of week Not reported 2.

Sitagliptin and vildagliptin (examined together) lowered A1c, fasting plasma glucose, and postprandial glucose when used as either monotherapy or add- on therapy compared with placebo, with or without additional oral hypoglycemic agents. When sitagliptin and vildagliptin were compared with other active oral hypoglycemic agents, the DPP- 4 inhibitors were slightly less effective in reducing A1c (pooled weighted mean difference in 2 A1c: 0. The results were pooled from 4 trials, 3 of which evaluated vildagliptin and included patients with baseline A1c of 8. Small increases in weight were also observed with sitagliptin when compared with placebo. When compared with glipizide or pioglitazone, sitagliptin had a more favorable weight profile. Metformin was the only comparator medication that exhibited weight loss. Both DPP-4 inhibitors were generally well tolerated; severe hypoglycemia was reported in only two patients receiving DPP-4 inhibitors across the included studies. No differences in risk of mild-to-moderate hypoglycemia or gastrointestinal adverse events were reported when sitagliptin and vildagliptin were compared to placebo. Results for sitagliptin and vildagliptin were not examined individually; vildagliptin is also not yet approved in the United States. This systematic review was considered low quality, as there was insufficient information about study selection criteria and individual study quality assessment. Thus, the study did not meet our inclusion criteria and we did not further evaluate its findings. For children and adults with type 2 diabetes, does sitagliptin differ in effectiveness, efficacy, and in harms for achieving glycemic control when compared to other hypoglycemic agents as monotherapy, combined therapy, or when compared to placebo? Evidence in children • Children and adolescents ≤ 18 years were not included in any of the published studies on effectiveness, efficacy, or harms. Evidence on long-term health outcomes and harms • No studies provided data on benefits or harms for follow-up periods longer than 52 weeks. Evidence on efficacy • When compared with placebo, sitagliptin 100 mg/d monotherapy significantly lowered A1c (pooled effect, between-group change -0. Diabetes Page 55 of 99 Final Report Drug Effectiveness Review Project • Though formal statistical analyses were not conducted for glipizide-or metformin monotherapy compared with sitagliptin monotherapy, it appears that sitagliptin may be comparable to glipizide and metformin 1 g/d in lowering A1c based on estimated magnitude of difference between groups. Additional trials are needed to verify the findings. Patients receiving glipizide or rosiglitazone gained weight compared with patients on sitagliptin who lost weight during the course of the trial. Harms • Weight generally decreased for both sitagliptin-treated and placebo-treated patients (range for change in weight from baseline: sitagliptin -0. Adjunctive therapy with sitagliptin also did not negatively affect weight, particularly in persons taking metformin; however, small increases in weight were seen when sitagliptin was added to sulfonylureas, pioglitazone, or rosiglitazone. There were 20 reports of severe hypoglycemia in 2 of 9 trials, mostly in patients taking glipizide (90%). The rates for total withdrawal were slightly lower with sitagliptin than compared with placebo (pooled RR 0. Diabetes Page 56 of 99 Final Report Drug Effectiveness Review Project Detailed Assessment Key Question 1 and 2. For children and adults with type 2 diabetes, does sitagliptin differ in efficacy, effectiveness, and in harms for achieving glycemic control when compared to placebo, when compared to other hypoglycemic agents as monotherapy or combined therapy, or when added to other hypoglycemic agents? Eight randomized controlled trials were rated fair-quality and 1 fair-poor. This review is organized by how sitagliptin was used (mono- or combined therapy compared with placebo or active control).
