This inertia reflects deep-rooted cultural and epistemological barriers that also impede the adoption of innovations such as Artificial Intelligence (AI). Yet, the call for more rigorous decision-making in medicine is not new. In the 18th century, Pierre-Simon Laplace emphasized the value of probability theory in clinical reasoning, a view later echoed by William Osler, who famously described medicine as \"the science of uncertainty and the art of probability.\" These early insights gained traction through the work of Sir Austin Bradford Hill and Archibald Cochrane, whose contributions laid the groundwork for Evidence-Based Practice (EBP). In the 1990s, Gordon Guyatt formally introduced Evidence-Based Medicine (EBM), advocating for clinical decisions grounded in empirical data, professional expertise, and patient values. In this evolving landscape, basic statistical literacy is no longer sufficient. In this context, cultivating probabilistic reasoning and statistical thinking has become essential to support ethically sound and evidence-aligned decisions to guide a meaningful transformation in both clinical training and practice.</p>","PeriodicalId":46305,"journal":{"name":"Trends in Psychiatry and Psychotherapy","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144498350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, whether this applies to university students, who commonly experience anxiety and depression, is less clear. This cross-sectional study explores the association of physical fitness with anxiety and depression symptoms in ≥18-year-old students from seven Brazilian universities. Mental health was evaluated using the Diagnostic and statistical manual of mental disorders (DSM-5), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7). Physical fitness was assessed via handgrip strength, vertical jump, and the 20m Shuttle-Run test, with students classified into low or high fitness based on genderspecific medians. Poisson regression with robust variance was used to analyze the relationship between physical fitness, anxiety, and depression. The sample included 199 students (52.6% women; median age=21).
