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

Four-dimensional (4D) echocardiography may provide more accurate estimations of left atrial (LA) volumes than 2-dimensional (2D) measures. We sought to compare the concordance of a novel 4D LA quantification software versus 2D echocardiography against cardiac magnetic resonance (CMR). This was a multimodality imaging substudy of a randomized clinical trial (the LOOP study). Elderly participants with stroke risk factors were included. A subgroup of this study population underwent transthoracic echocardiography (n = 1441) and a subset underwent CMR within two weeks (n = 73). The mean age of the echocardiographic study population was 74 years and 54% were men. The maximal LA volume (LAVmax) was 47 mL by 2D, 52 mL by 4D, and 104 mL by CMR. While 2D echocardiography showed a moderate correlation with 4D (R
