Relationship Between Image Quality and Bias in 3D Echocardiographic Measures: Data From the SABRE (Southall and Brent Revisited) Study.
Observational study in Journal of the American Heart Association, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Background Image-quality (IQ) compromises left ventricle assessment by 3-dimensional echocardiography (3DE). Sicker/frailer patients often have suboptimal IQ, and therefore observed associations may be biased by IQ. We investigated its effect in an observational study of older people and when IQ was modified experimentally in healthy volunteers. Methods and Results 3DE feasibility by IQ was assessed in 1294 individuals who attended the second wave of the Southall and Brent Revisited study and was compared with 2-dimensional (2D)-echocardiography feasibility in 147 individuals. Upon successful analysis, means of ejection fraction (3D-EF) and global longitudinal strain (3D-GLS) (plus 2D-EF) were compared in individuals with poor versus good IQ. In 2 studies of healthy participants, 3DE-IQ was impaired by (1) intentionally poor echocardiographic technique, and (2) use of a sheet of ultrasound-attenuating material (neoprene rubber; 2-4 mm). The feasibility was 41% (529/1294) for 3DE versus 61% (89/147) for 2D-EF,
