To investigate the relationship between future or unknown outcomes and baseline health states among people with specific conditions, prediction models are an interesting strategy used to assist diagnosis, prognosis and treatment. They estimate the likelihood of clinical events taking into account clinical relevant measures and complementary tests. These predictors and their importance vary between the different events of interest and their prediction ability varies when considered singly or in combination with other predictors. They may facilitate simple and direct comparisons […]

Abstract Background: The SAMe-TT2R2 score was developed to predict which patients on oral anticoagulation with vitamin K antagonists (VKAs) will reach an adequate time in therapeutic range (TTR) (> 65%-70%). Studies have reported a relationship between this score and the occurrence of adverse events. Objective: To describe the TTR according to the score, in addition to relating the score obtained with the occurrence of adverse events in patients with nonvalvular atrial fibrillation (AF) on oral anticoagulation with VKAs. Methods: Retrospective […]
