Tricuspid Valve Size Relationship to Right Ventricular Volume in Post-operative Tetralogy of Fallot Patients.
Article in Pediatric cardiology, 2022. 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
In post-operative Tetralogy of Fallot (TOF) patients cMRI data are used for determining right ventricle (RV) dilation to justify the pulmonary valve placement. Echocardiogram analysis of RV volumes has inherent accuracy issues. There are no data exploring the relationship of transthoracic echocardiography tricuspid valve (TV) annulus size and cMRI RV dilation. Retrospective study in post-operative TOF patients. Patients less than 21 years old and with high-quality transthoracic echocardiogram and MRI within 6 months of each other were included. We collected demographic data, type of initial repair, echocardiographic, and cMRI data. A single reviewer measured echocardiogram TV size. Boston z-scores were used. 77 echocardiogram and cMRI pairs were analyzed. Average age was 14 years old. There is not a strong linear relationship between TV z-score and indexed right ventricular end diastolic volume (RVEDVi) (R
