В соответствии с концепцией доказательной медицины методологическое качество исследования определяется двумя его аспектами: рисками систематических ошибок и рисками некорректности анализа данных. Минимизация обоих рисков повышает внутреннюю валидность исследования. Существуют многочисленные рекомендации и руководства по проведению статистического анализа данных в медицинских исследованиях и его представлению в публикациях, однако до настоящего времени международным сообществом не был выработан какой-либо формализованный вопросник для оценки качества статистического анализа, который был бы предназначен для рецензентов.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ. Разработать инструмент формализованной оценки качества статистического анализа, представленного в научных медицинских публикациях.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ. Вопросник разработан на основе многолетнего опыта авторов в области статистического анализа данных и рецензирования статистических аспектов статей и диссертаций. При разработке вопросника принимались во внимание рекомендации SAMPL, документ ICH E9 и другие рекомендации. Выполнена внутренняя валидизация вопросника, заключавшаяся в проведении независимой оценки двумя экспертами 20 случайно отобранных в elibrary.ru статей о рандомизированных контролируемых испытаниях (РКИ), и дальнейшем статистическом анализе согласованности заключений экспертов.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Разработан вопросник CORSTAN (CORrect STatistical ANalysis), состоящий из двух частей: первая часть (10 вопросов) предназначена для оценки исследований любых дизайнов, вторая (8 вопросов) – для дополнительной оценки РКИ. Предложена стратификация риска некорректности статистического анализа. Оценка внутренней валидности вопросника показала ее высокий уровень как в отношении согласованности оценок рецензентов по каждому из вопросов, так и в отношении оценки каждой из статей как по сумме баллов, так и по уровню риска некорректности статистического анализа.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Использование вопросника и шкалы позволит упростить и гармонизировать статистическое рецензирование публикаций и рукописей в различных институциях – научных журналах, диссертационных советах и т.д. Вопросник также может быть полезен и авторам в процессе подготовки рукописей, он будет способствовать повышению качества не только публикаций, но и самих исследований. Мы планируем усовершенствовать вопросник по мере накопления опыта его применения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: In evidence-based medicine, the research methodology is determined by the risks of systematic biases and incorrect data analysis. Minimizing both risks increases the internal validity of the study. There are numerous recommendations and guidelines for data analysis and reporting, but the international community has not yet developed a questionnaire for reviewers to assess the quality of statistical analysis.</p></sec><sec><title>AIM</title><p>AIM: To develop a tool for formalized assessment of the quality of statistical analysis presented in scientific medical publications.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The questionnaire was developed based on the authors' decades of experience in statistical data analysis and reviewing the statistical aspects of biomedical articles and dissertations. The SAMPL guidelines, ICH E9, and other guidelines were taken into account when developing the questionnaire. Internal validation of the questionnaire was based on an independent assessment by two experts of 20 randomly selected articles on randomized controlled trials (RCTs) from elibrary.ru, and further statistical analysis of the agreement of experts' conclusions.</p></sec><sec><title>RESULTS</title><p>RESULTS: The CORSTAN (CORrect STatistical ANalysis) questionnaire was developed, which consists of two parts: the first part (10 questions) is intended for evaluating studies of any designs, while the second (following eight questions) is for additional assessment of RCTs. A stratification of the risk of incorrect statistical analysis is proposed. The evaluation of the questionnaire's internal validity showed its substantial and almost perfect agreement for each question and each article both in the sum of points and risk level.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: The use of the questionnaire will simplify and harmonize the statistical review of publications and manuscripts in various institutions - scientific journals, dissertation boards, etc. The questionnaire can also be helpful for authors during preparing manuscripts; it will also help improve the quality of publications and research itself. We plan to improve the questionnaire as we gain experience in its application.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>доказательная медицина</kwd><kwd>методологическое качество</kwd><kwd>анализ данных</kwd><kwd>статистический анализ</kwd><kwd>ошибки</kwd><kwd>вопросник</kwd><kwd>CORSTAN</kwd><kwd>валидность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>evidence-based medicine</kwd><kwd>research integrity</kwd><kwd>data analysis</kwd><kwd>biostatistics</kwd><kwd>scale</kwd><kwd>questionnaire</kwd><kwd>CORSTAN</kwd><kwd>validity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">нет</funding-statement><funding-statement xml:lang="en">None.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Реброва О.
