В условиях расширения практики переноса единственного эмбриона выбор наиболее компетентного эмбриона становится критически значимым для достижения высоких репродуктивных исходов. Морфологическая оценка, включая классификациюь Гарднера, остаётся широко используемым инструментом, однако её прогностическая ценность остаётся ограниченной и вариабельной. Технология покадровой съёмки (time-lapse) позволяет регистрировать морфокинетические параметры эмбрионов и формировать алгоритмы прогнозирования имплантации на основе временных характеристик ключевых этапов развития. Исследования показывают влияние ряда факторов — возраста женщины, массы тела, курения, эндометриоза — на параметры морфокинеза, при этом преимущества TLM над традиционным культивированием всё ещё не имеют окончательных доказательств. Тем не менее использование time-lapse может повысить точность отбора эмбрионов, включая выбор кандидата для переноса или ПГ-Т-А, что особенно важно у пациенток старшего репродуктивного возраста.</p></sec><sec><title>   Цель</title><p>   Цель. определить прогностические факторы положительного исхода программы ЭКО на основе анализа классификационного дерева.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. Исследованы данные 431 циклов ЭКО. Положительным исходом считалось наступление клинической беременности, отрицательным — её отсутствие. Для выявления значимых предикторов использован метод CHAID. В анализ включены показатели возраста пациентки и морфокинетические параметры развития эмбриона к 5 суткам культивирования.</p></sec><sec><title>   Результаты</title><p>   Результаты. Ключевым разделяющим фактором оказался возраст пациентки ≤ 35 лет (p = 0,004). В этой группе частота положительных исходов составила 47,8 %, против 31,0 % у пациенток старше 35 лет. Среди женщин ≤ 35 лет наиболее значимым фактором являлось значение баллов морфокинетической оценки (балл по AI за 5 сутки, p = 0,001): при балле &gt; 9,4 вероятность положительного исхода достигала 72,5 %, в то время как при ≤ 5,1 — лишь 30,3 %. У пациенток старше 35 лет аналогичная закономерность сохранялась (p &lt; 0,001), однако частота положительных исходов при высоких баллах снижалась до 46,5 %.</p></sec><sec><title>   Заключение</title><p>   Заключение. Возраст пациентки и морфокинетическая оценка эмбриона являются независимыми предикторами успеха программы ЭКО. Использование дерева классификации позволяет персонализировать прогноз исхода и оптимизировать тактику переноса эмбрионов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. With the expansion of single embryo transfer practices, selecting the most competent embryo is becoming critical for achieving high reproductive outcomes. Morphological assessment, including the Gardner classification, remains a widely used tool; however, its prognostic value remains limited and variable. Time-lapse imaging technologyallows for recording embryo morphokinetic parameters and developing implantation prediction algorithms based on the timing of key developmental stages. Research shows the influence of a number of factors — woman’s age, body weight, smoking, and endometriosis — on morphokinetic parameters. However, the advantages of TLM over traditional culture remain unclear. Nevertheless, the use of time-lapse imaging can improve the accuracy of embryo selection, including the selection of candidates for transfer or PGT-A, which is particularly important in patients of advanced reproductive age.</p></sec><sec><title>   Objective</title><p>   Objective. To identify prognostic factors for a positive IVF outcome based on classification tree analysis.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. Data from 431 IVF cycles were analyzed. A positive outcome was defined as clinical pregnancy, and a negative outcome was defined as its absence. The CHAID method was used to identify significant predictors. The analysis included patient age and morphokinetic parameters of embryo development by day 5 of culture.</p></sec><sec><title>   Results</title><p>   Results. The key discriminatory factor was patient age (≤ 35 years) (p = 0.004). In this group, the success rate was 47.8 %, compared to 31.0 % in patients over 35 years of age. Among women ≤ 35 years of age, the most significant factor was the morphokinetic assessment score (AI score on day 5, p = 0.001): with a score &gt; 9.4, the probability of a successful outcome reached 72.5 %, while with a score ≤ 5.1, it was only 30.3 %. A similar pattern persisted in patients over 35 years of age (p &lt; 0.001), but the success rate with high scores decreased to 46.5 %.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Patient age and embryo morphokinetic assessment are independent predictors of IVF success. Using a classification tree allows for personalized outcome prognosis and optimized embryo transfer strategies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ЭКО</kwd><kwd>эмбрионы</kwd><kwd>морфокинетика</kwd><kwd>классификационное дерево</kwd><kwd>возраст</kwd><kwd>прогноз исхода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IVF</kwd><kwd>embryos</kwd><kwd>morphokinetics</kwd><kwd>classification tree</kwd><kwd>age</kwd><kwd>outcome prognosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы заявляют об отсутствии спонсорской поддержки при проведении исследования</funding-statement><funding-statement xml:lang="en">The authors declare no sponsorship support for this study</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">Gardner DK, Lane M.
