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

aimsThere is limited information on the association between left ventricular (LV) dimensions and cardiovascular (CV) outcomes in patients with heart failure (HF) with reduced LV ejection fraction (HFrEF) receiving recommended HF treatment. We investigated the association between LV dimensions and CV outcomes in HFrEF patients receiving recommended HF treatment. METHODS AND

resultsWe investigated the association between LV echocardiographic dimensions and CV outcomes using conventional Cox models in 1138 HFrEF patients in sinus rhythm randomized to warfarin or aspirin treatment in the Warfarin vs. Aspirin in Reduced Cardiac Ejection Fraction (WARCEF) trial. LV enlargement, whether by diameter [LV end-diastolic diameter index (LVEDDI) and LV end-systolic diameter index (LVESDI)] or volume [LV end-diastolic volume index (LVEDVI) and LV end-systolic volume index (LVESVI)], was independently associated with all-cause death [LVEDDI: hazard ratio (HR) per cm/m

conclusionsLeft ventricular enlargement is an independent predictor of CV events in patients with HFrEF and recommended HF treatment. LV dimensions should be considered in the risk assessment.
