SAMe-TT2R2 Score in the Outpatient Anticoagulation Clinic to Predict Time in Therapeutic Range and Adverse Events.
Article in Arquivos brasileiros de cardiologia, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 cohort study including patients with nonvalvular AF attending an outpatient anticoagulation clinic of a tertiary hospital. Visits to the outpatient clinic and emergency, as well as hospital admissions to the institution, during 2014 were evaluated. The TTR was calculated through the Rosendaal´s method. Results: We analyzed 263 patients (median TTR, 62.5%). The low-risk group (score 0-1) had a better median TTR as compared with the high-risk group (score ≥ 2): 69.2% vs. 56.3%, p = 0.002. Similarly, the percentage of patients with TTR ≥ 60%, 65% or 70% was higher in the low-risk group (p < 0.001, p = 0.001 and p = 0.003, respectively). The high-risk group had a higher percentage of adverse events (11.2% vs. 7.2%), although not significant (p = 0.369). Conclusions: The SAMe-TT2R2 score proved to be effective to predict patients with a better TTR, but was not associated with adverse events. Fundamento: O escore SAMe-TT2R2 foi desenvolvido visando predizer quais pacientes em anticoagulação oral com antagonistas da vitamina K (AVKs) atingirão um tempo na faixa terapêutica (TFT) adequado (> 65%-70%) no seguimento. Estudos também o relacionaram com a ocorrência de eventos adversos. Objetivos: Descrever o TFT de acordo com o escore, além de relacionar a pontuação obtida com a ocorrência de eventos adversos adversos em pacientes com fibrilação atrial (FA) não valvar em anticoagulação oral com AVKs. Métodos: Estudo de coorte retrospectivo incluindo pacientes com FA não valvar em acompanhamento em ambulatório de anticoagulação de um hospital terciário. Foi realizada uma avaliação retrospectiva de consultas ambulatoriais, visitas a emergência e internações hospitalares na instituição no período de janeiro-dezembro/2014. O TFT foi calculado aplicando-se o método de Rosendaal. Resultados: Foram analisados 263 pacientes com TFT mediano de 62,5%. O grupo de baixo risco (0-1 ponto) obteve um TFT mediano maior em comparação com o grupo de alto risco (≥ 2 pontos): 69,2% vs. 56,3%, p = 0,002. Da mesma forma, o percentual de pacientes com TFT ≥ 60%, 65% ou 70% foi superior nos pacientes de baixo risco (p < 0,001, p = 0,001 e p = 0,003, respectivamente). Os pacientes de alto risco tiveram um percentual maior de eventos adversos (11,2% vs. 7,2%), embora não significativo (p = 0,369). Conclusões: O escore SAMe-TT2R2 foi uma ferramenta eficaz na predição do TFT em pacientes com FA em uso de AVKs para anticoagulação, porém não se associou à ocorrência de eventos adversos.
