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

We conducted this study to investigate left ventricle (LV) systolic function in endocardial, mid-myocardial, and epicardial layers by two-dimensional (2D) speckle tracking echocardiography (STE) in hypertrophic cardiomyopathy (HCM) patients with myocardial injury indexed by elevated serum cardiac troponin I (cTnI). Twenty-nine HCM patients with myocardial injury, thirty-five HCM patients without myocardial injury, and ninty-one healthy controls were enrolled in this study. Serum cTnI > 0.026 ng/mL was defined as myocardial injury. LV longitudinal and circumferential strain (LS and CS) were assessed in endocardial, mid-myocardial and epicardial layers. Layer-specific LS and CS differed significantly (all P < 0.001) among all three groups in all three layers, in a descending order from healthy controls to HCM patients without myocardial injury to HCM patients with myocardial injury. Layer-specific LS and CS were decreased the most in HCM patients with myocardial injury indexed by elevated seum cTnI (all P < 0.05). In HCM patients with myocardial injury, layer-specific LS and CS were significantly lower in the segments with greater hypertrophy (segmental thickness ≥ 15 mm) (all P < 0.001) except for endocardial CS (P > 0.05). Layer-specific evaluation of LV strain may improve understanding of impaired LV systolic function in HCM patients with myocardial injury, thus preventing further damage.
