🔬Search and selection of studies

Meta-analysis begins not with averaging effects, but with a transparent search of the literature, inclusion and exclusion criteria, so that the final conclusion does not depend on the convenient manual selection of articles.

Systematic literature search
A good meta-analysis begins with a well-thought-out search strategy across databases, keywords, and time frames, rather than a convenient selection of familiar articles.
PRISMA as selection transparency
PRISMA helps show the entire path of selecting studies: how many records were found, how many were discarded, and for what reasons the final corpus turned out to be the way it was.
Inclusion and exclusion criteria
Selection criteria are needed to ensure that the decision to include a study depends on explicit rules, and not on whether the author likes the result obtained in it.

# Поиск и отбор исследований Мета-анализ начинается не с усреднения эффектов, а с прозрачного поиска литературы, критериев включения и исключения, чтобы итоговый вывод не зависел от удобного ручного отбора статей. Эта тема раскрывает узел "Методология мета-анализа" и нужна для того, чтобы карта не заканчивалась общим названием без внутренней структуры.
