Left ventricular quantification in repaired tetralogy of Fallot: two-dimensional echocardiography versus cardiovascular magnetic resonance.
Article in The international journal of cardiovascular imaging, 2026. 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
Left ventricular (LV) dysfunction is a known risk factor for adverse outcomes in patients with repaired tetralogy of Fallot (rTOF). While cardiovascular magnetic resonance (CMR) is the reference standard for LV assessment, two-dimensional echocardiography (2DE) remains the most accessible tool for surveillance. The accuracy of commonly used 2DE methods, Simpson's biplane (SiBP) and 5/6 area-length (AL), in the setting of right ventricular (RV) dilation and altered interventricular septum configuration remains uncertain. We conducted a retrospective analysis of pediatric patients with rTOF seen between 2013 and 2023 who underwent both CMR and 2DE within a 90-day interval. Patients were excluded if an intervention occurred between studies. LV end-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction (EF) were measured using SiBP and AL methods and compared to CMR values. Agreement was compared using standard agreement metrics, with subgroup analyses stratified by RV dilation severity. 2DE reproducibility was assessed using intraclass correlation coefficient (ICC). Of 154 patients (2013-2023), 62 met inclusion criteria based on image quality. Median age at CMR was 15 years, with median indexed RVEDV of 137 mL/m
