01Introduction to Reviews and Study DesignsThe nine steps of a systematic review, what distinguishes it from the other kinds of review, which study designs belong in one, and the team and timeline a review actually requires.انگلیسی40 دقیقه02The Review Question and Inclusion CriteriaTurning a topic into a review question that determines everything downstream. Choosing outcomes that decision makers actually need, rating their importance, and using analytic frameworks when the question has more than one link.انگلیسی40 دقیقه03Searching and ScreeningBuilding a search that finds the studies, understanding the dissemination biases that make an incomplete search dangerous, and screening thousands of records reproducibly.انگلیسی45 دقیقه04Data Abstraction, Forms, and NumbersExtracting what synthesis actually requires. The numbers needed for dichotomous and continuous outcomes, how to handle loss to follow-up and the intention-to-treat principle, and what to do when the paper does not report what you need.انگلیسی45 دقیقه05Risk of Bias in Randomized TrialsThe biases that threaten a randomized trial, the empirical evidence for how much each distorts results, and how to apply the Cochrane RoB 2 tool domain by domain.انگلیسی45 دقیقه06Risk of Bias in Non-Randomized StudiesWhen trials are absent or cannot answer the question, non-randomized studies must be appraised against what a well-conducted trial would have shown. The ROBINS-I tool, the target trial idea, and why applicability is a separate judgment.انگلیسی45 دقیقه07Principles of Meta-Analysis, Part 1Why pool at all, whether these studies should be combined, and how to compute and read a pooled estimate for dichotomous and continuous outcomes. Worked entirely by hand before touching software.انگلیسی50 دقیقه08Principles of Meta-Analysis, Part 2Fixed-effect and random-effects models and what each is estimating, the generic inverse variance method for data that do not fit the standard forms, handling rare events and zero cells, and assessing publication bias.انگلیسی50 دقیقه09Heterogeneity, Subgroups, and Narrative SynthesisWhat to do when the studies disagree. Distinguishing clinical from statistical heterogeneity, investigating it with subgroups and meta-regression, and conducting a structured synthesis when pooling is not possible or not appropriate.انگلیسی45 دقیقه10Interpreting Results and GRADEA pooled estimate is not an answer until you know how much to believe it. Converting relative effects to absolute ones, and the five domains that lower certainty and the three that raise it.انگلیسی50 دقیقه11Summary of Findings Tables and Using the EvidenceBuilding the one table that carries a review's answer, writing conclusions that match the evidence, reporting the review to PRISMA, and the path from a review to a recommendation.انگلیسی45 دقیقه
