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

Left atrium (LA) function is a known predictive marker of heart failure in adults. Few reports of LA function analyses using LA strain (ɛ) and strain rate (SR) measurements in children exist. Thus, this study aimed to determine normal reference values for LA ɛ and SR in healthy school children and to investigate methods of interpreting LA function data based on maturational changes using two-dimensional speckle-tracking echocardiography (2DSTE). We recruited 112 healthy school children (median age 12.0 years; range 6-16 years). LA ɛ and SR were investigated using 2DSTE multi-vendor analysis software (TomTec Imaging Systems, Germany) and compared to Doppler parameters and LA volumes measured by the conventional method. The onset of the P wave was selected as the reference point for the LA ɛ analysis. Normal ranges of LA ɛ [reservoir (ɛRS), conduit (ɛCD), or contractile (ɛCT)] and positive SR (SR
