Comparison of multiple risk scores in assessing medium-to long-term clinical outcomes in unstable angina / non-ST-elevation myocardial infarction patients undergoing multi vessel percutaneous coronary intervention: An observational, registry-based study in India.

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
objectivePost-revascularization mortality in multivessel coronary artery disease (MVCAD) has been explored via several risk scores. Here, we assessed and compared various risk scores in predicting medium to long-term clinical outcomes in unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI) patients with MVCAD undergoing percutaneous coronary intervention (PCI).
methodsWe analyzed a cohort of a tertiary care center registry enrolling patients in South India, Kerala, with MVCAD (N = 200) who had undergone PCI between 2010 and 2018. The outcomes evaluated were all-cause mortality and major adverse cardiac events (MACE). The risk scores assessed included SYNTAX score (SS), residual SYNTAX score (rSS), SYNTAX revascularization index (SRI), age, creatinine, and ejection fraction (ACEF) score, clinical SYNTAX score (cSS), and SYNTAX score II (SSII).
resultsOf the analyzed risk scores, SSII had the best predictive capability with the area under the curve (AUC) of 0.79 in c-statistics, followed by ACEF score and cSS with AUCs of 0.74 and 0.65, respectively for all-cause mortality (p < 0.01). Kaplan-Meier survival curves and multivariate analysis by Cox regression showed SSII with cut-offs of >35.15 and > 29.55 to be the only score associated with higher mortality and MACE, respectively.
conclusionsIn UA/NSTEMI patients with relatively less complex MVCAD treated by PCI, the SSII, ACEF and cSS risk scores could predict the outcomes better. The SSII showed the best predictive performance for all-cause mortality and MACE. Scores based on baseline and residual atherosclerotic burden (SS, rSS, and SRI) performed poorly in predicting the mortality and MACE.
