TIMI Risk Score for Secondary Prevention to Risk Stratify Chronic Coronary Syndrome Patients: External Validation Study.
Article in Arquivos brasileiros de cardiologia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundRisk stratification in chronic coronary syndrome (CCS) patients is challenging. TIMI Risk Score for Secondary Prevention (TRS2P) is a simple nine-point tool developed to predict cardiovascular death, myocardial infarction (MI), and ischemic stroke among post-MI patients. No studies have been conducted on it in the Brazilian population.
objectiveValidate the TRS2P score among CCS patients at a tertiary center in Brazil.
methodsThis is a registry-based study of patients with CCS, defined as having a previous revascularization procedure, previous MI, or ≥50% stenosis in at least one epicardial coronary artery. The primary outcome was the three-year incidence of MACE (death, MI or stroke). The predicted risk was as reported in the original derivation study. Calibration was assessed through a calibration plot and the Hosmer-Lemeshow test. Discrimination was evaluated through the concordance (C)-statistic. A significance level of 0.05 was adopted.
resultsThe study sample consisted of 515 patients. There were 173 (34%) women, 75 (15%) aged over 75 years, 298 (58%) had diabetes, and 156 (30%) had chronic kidney disease. During follow-up, 126 MACE were documented. The estimated three-year incidence was 24% (95% confidence interval [CI] 21%-28%), whereas the predicted incidence was 15%. Although higher TRS2P scores were associated with higher MACE incidence, the TRS2P risk score model underestimated MACE incidence at every strata (p < 0.01). The C-statistic was 0.64 (95% CI 0.58-0.69).
conclusionThe TRS2P score identifies patients with a higher risk of cardiovascular events but it underestimated MACE and presented poor discrimination in a Brazilian CCS cohort.
