Determinants of image quality in transthoracic echocardiography: A retrospective cohort study.
Article in JRSM cardiovascular disease. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: To identify patient factors associated with poor transthoracic echocardiographic image quality and to evaluate whether a simple pre-test triage model could improve imaging efficiency. Design: Retrospective cohort study with derivation and independent validation cohorts, together with a model-based cost-effectiveness analysis. Setting: Single large UK tertiary centre using routinely collected data from 2010 to 2020. Participants: 70,597 adult transthoracic echocardiograms, divided into a derivation cohort (n = 40,000) and an independent validation cohort (n = 30,597). Main outcome measures: Poor image quality (limited or non-diagnostic vs good or adequate), model discrimination, sensitivity, specificity and comparative imaging costs. Results: Of 70,597 studies, 24,213 (34.3%) were poor quality, including 8582 (12.2%) non-diagnostic and 15,631 (22.1%) limited studies. Lung disease was the strongest predictor (OR 2.04, 95% CI 1.59 to 2.61), followed by suspected heart failure, inpatient status, arrhythmia, prior cardiac surgery and permanent pacemaker (all Conclusions: Several routinely available clinical factors influence transthoracic echocardiographic image quality. Although individual-level prediction is modest, pre-test triage may help direct higher-risk patients to contrast echocardiography or alternative imaging, reducing repeat testing and improving efficiency.
