1 · What the graph read from it

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.

2 · The registry

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

backgroundThe predictive value of left ventricular (LV) global longitudinal strain (GLS) to predict outcomes in different left ventricular ejection fraction (LVEF) cohorts is not well known. We aimed to assess the role of LV GLS predicting outcomes in HF patients by LVEF.

methodsIn the Multicenter Automatic Defibrillator Implantation Trial Cardiac Resynchronization Therapy (MADIT-CRT), we studied 1077 patients (59%) with 2D speckle tracking data available, 437 patients with LVEF > 30% and 640 with LVEF ≤ 30%. Baseline LV GLS was stratified in tertiles in both LVEF subgroups. The primary endpoint was ventricular tachycardia/fibrillation (VT/VF) or death; the secondary endpoint was heart failure (HF) or death.

resultsIn patients with LVEF ≤ 30%, a higher tertile GLS (T3, less contractility) was associated with a higher rate of VT/VF/death (P < 0.001), with similar association in patients with LVEF > 30% (P = 0.057). In patients with LVEF ≤ 30%, a higher tertile GLS was also associated with a higher rate of HF/death. In multivariable models, LV GLS predicted VT/VF or death in the LVEF ≤ 30% subgroup [T1 vs. T2/3 HR = 1.67 (1.16-2.38), P = 0.005], but not in those with LVEF > 30% [T1 vs. T2.3 HR = 1.32 (0.86-2.04), P = 0.21]. LV GLS predicted HF/death in the LVEF ≤ 30% subgroup [T1 vs T2/3 HR = 2.00 (1.30-3.13), P = 0.002], but not in in those with LVEF > 30%.

conclusionsIn this MADIT-CRT sub-study, LV GLS identified patients at higher risk of VT/VF, HF/death risk independently of conventional clinical parameters in patients with LVEF ≤ 30%, but not in patients with LVEF > 30%.
