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

Aims: Global longitudinal strain (GLS) is a sensitive measure of left ventricular (LV) function, though hampered by significant variability. Data on how echocardiographic recordings and measurements influence GLS and its variability are scarce. We aimed to study the consequences of variability in echocardiographic recordings and measurement procedures for GLS in a normal population. Methods and results: Healthy participants ( Conclusion: Using novel DL methodology and available metadata, we found that indicators of image standardization and measurement procedures influenced GLS. Implementing such quality indicators during recording and measurement procedures may improve the efficacy of echocardiography and ease the interpretation of differences between studies.
