Relevant review articles order genuine alendronate on-line womens health vero beach, meta-analyses order 35 mg alendronate overnight delivery menstrual migraine symptoms, and methods articles were flagged for ES-6 manual searching of references and cross-referencing against the library of citations identified through electronic database searching. All screening decisions were made and tracked in a DistillerSR database (Evidence Partners Inc. Data Extraction The research team created data abstraction forms and evidence table templates for each KQ. Based on clinical and methodological expertise, a pair of investigators was assigned to abstract data from each eligible article. One investigator abstracted the data, and the second reviewed the completed abstraction form alongside the original article to check for accuracy and completeness. Quality Assessment of Individual Studies We evaluated the quality of individual studies using the approach described in the Methods 23 Guide. Criteria of interest for all studies included similarity of groups at baseline, extent to which outcomes were described, blinding of subjects and providers, blinded assessment of the outcome(s), intention-to-treat analysis, and differential loss to followup between the compared groups or overall high loss to followup. Criteria specific to RCTs included methods of randomization and allocation concealment. For observational studies, additional elements such as methods for selection of participants, measurement of interventions/exposures, addressing any design-specific issues, and controlling for confounding were considered. We summarized our assessments by assigning overall ratings of good, fair, or poor to each study. Data Synthesis We began our data synthesis by summarizing key features of the included studies for each KQ: patient characteristics; clinical settings; interventions; and intermediate, final, and adverse event outcomes. We grouped interventions by drug class; in this context, we considered all non- dihydropyridine calcium channel blocker drugs to be similar enough to be grouped together and all beta blocker drugs to be similar enough to be grouped together. Similarly, we categorized procedures into electrical cardioversion, AVN ablation, AF ablation by PVI (either open surgical, minimally invasive, or transcatheter procedures), and surgical Maze procedures, and explored comparisons among these categories. For the KQs focusing on pharmacological agents versus procedures (KQ 3 and KQ 5), we also explored grouping all pharmacological agents together and comparing them with all procedures. Finally for our evaluation of rate- versus rhythm-control strategies (KQ 6), we grouped all rate-control strategies together and all rhythm- control strategies together regardless of the specific agent or procedure. We determined the appropriateness of a quantitative synthesis (i. Where at least three comparable studies reported the same outcome, we used random-effects models to synthesize the available evidence quantitatively using Comprehensive Meta-Analysis software (Version 2; Biostat, Englewood, NJ). We tested for heterogeneity using graphical displays and test statistics ES-7 2 (Q and I statistics), while recognizing that the ability of statistical methods to detect heterogeneity may be limited. For comparison, we also performed fixed-effect meta-analyses. We present summary estimates, standard errors, and confidence intervals in our data synthesis. Unless noted otherwise, when we were able to calculate odds ratios (ORs), we assumed that an OR between 0. Strength of the Body of Evidence We rated the strength of evidence for each KQ and outcome using the approach described in 23,28 the Methods Guide. In brief, the approach requires assessment of four domains: risk of bias, consistency, directness, and precision. Additional domains were used when appropriate: strength of association (magnitude of effect) and publication bias (as assessed through a search of ClinicalTrials. These domains were considered qualitatively, and a summary rating of high, moderate, or low strength of evidence was assigned after discussion by two reviewers. In some cases, high, moderate, or low ratings were impossible or imprudent to make—for example, when no evidence was available or when evidence on the outcome was too weak, sparse, or inconsistent to permit any conclusion to be drawn. In these situations, a grade of insufficient was assigned. Applicability We assessed applicability across the KQs using the method described in the Methods 23,29 Guide. In brief, we used the PICOTS format to organize information relevant to applicability. The most important applicability issue is whether the outcomes observed in any individual study, with its specific patient population and method of implementing treatments, can confidently be extrapolated to a broader context. We used these data to evaluate the applicability to clinical practice, paying special attention to study eligibility criteria, demographic features of the enrolled population compared with the target population, characteristics of the intervention used compared with care models currently in use, and clinical relevance and timing of the outcome measures. We summarized issues of applicability qualitatively. Results Figure B depicts the flow of articles through the literature search and screening process. Searches of PubMed, Embase, and CDSR yielded 8,103 unique citations. Manual searching of gray literature databases, bibliographies of key articles, and information received through requests for scientific information packets identified 224 additional citations, for a total of 8,327 citations. After applying inclusion/exclusion criteria at the title-and-abstract level, 505 full-text articles were retrieved and screened. Of these, 323 were excluded at the full-text screening stage, leaving 182 articles for data abstraction. The relationship of studies to the review questions is as follows: 14 studies relevant to KQ 1, 3 ES-8 studies relevant to KQ 2, 6 studies relevant to KQ 3, 42 studies relevant to KQ 4, 83 studies relevant to KQ 5, and 14 studies relevant to KQ 6. The full report provides a detailed list of included articles, along with a complete list of articles excluded at the full-text screening stage, with reasons for exclusion. As described in the Methods chapter of the full report, we searched ClinicalTrials. We acknowledge that this is not an exhaustive strategy, as several other registries also exist with differing geographical focus and varying degrees of overlap in their trial listings; however, in the opinion of the investigators, the large, widely used, U. The sample sizes of the potentially relevant unpublished studies we identified corresponded to 8 percent of the included population for published studies relevant to KQ 1 and 12 percent for KQ 5. Because of the relatively low proportion of unpublished studies identified through our ClinicalTrials. Literature flow diagram aSome studies were relevant to more than one KQ. Note: CRT = cardiac resynchronization therapy; KQ = Key Question; RCT = randomized controlled trial. Rate-Control DrugsKey points from the Results chapter of the full report are as follows: • Based on three studies (two good, one fair quality) involving 271 patients, evidence suggests that amiodarone is comparable to the calcium channel blocker diltiazem for rate control (low strength of evidence). ES-10 • Many outcomes/comparisons were rated to have insufficient strength of evidence. These include improvement of AF symptoms in patients receiving combined treatment with carvedilol plus digoxin compared with digoxin alone, rate control in patients using metoprolol versus diltiazem or sotalol, and the safety of any one pharmacological agent used for ventricular rate control in patients with AF. A total of 14 RCTs involving 1,017 patients were identified that assessed the use of pharmacological agents for ventricular rate control in patients with AF. Six studies were considered to be of good quality, eight of fair quality, and none of poor quality.
