The Incremental Prognostic Value of E/(e'×s') Ratio in Non-ST-Segment Elevated Acute Coronary Syndrome.

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
It has been shown that the E/(e'×s') index, which associates a marker of diastolic function (E/e', early transmitral/diastolic mitral annulus velocity ratio) and a parameter that explores LV systolic performance (s', systolic mitral annulus velocity), is a good predictor of outcome in acute anterior myocardial infarction. There are no studies that have investigated the prognostic value of E/(e'×s') in a non-ST-segment elevated acute coronary syndrome (NSTE-ACS) population. Echocardiography was performed in 307 consecutive hospitalized patients with NSTE-ACS and succesful percutaneous coronary intervention, before discharge and six weeks after. The primary endpoint consisted of cardiac death or readmission due to re-infarction or heart failure. During the follow-up period (25.4 ± 3 months), cardiac events occurred in 106 patients (34.5%). Receiver operating characteristic (ROC) analysis identified E/(e'×s') at discharge as the best independent predictor of composite outcome. The optimal cut-off value was 1.63 (74% sensitivity, 67% specificity). By multivariate Cox regression analysis, E/(e'×s') was the only independent predictor of cardiac events. Kaplan-Meier analysis identified that patients with an initial E/(e'×s') > 1.63 that worsened after six weeks presented the worst prognosis regarding composite outcome, readmission, and cardiac death (all
