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

The optimal post-repair pulmonary valve annulus (PVA) diameter in tetralogy of Fallot (TOF) may be far smaller than anticipated. Therefore, selected patients can undergo repair without manipulating the PV structure. Of the 347 patients who underwent TOF repair with PVA preservation (AP) from January 2016 to December 2023, 100 had AP while leaving the PV structure untouched. Median age, weight, and PVA (Z) at repair were 125 days (interquartile range [IQR], 96.5-167.5), 6.3 kg (IQR, 5.1-7.1), and -0.8 (IQR, -1.8 to 0.3), respectively. One non-cardiac late death occurred 9 months after repair. During a median 46.2 months follow-up, 14 patients (14%) required reinterventions for significant right ventricular outflow tract obstruction (RVOTO): balloon pulmonary valvuloplasty (BPV) in 6, surgical RVOTO relief in 4, and BPV followed by surgery in 4 (including 1 who received a right ventricle to pulmonary artery conduit to bypass a left anterior descending coronary artery crossing the RVOT). Except for the conduit recipient, only 2 patients showed significant RVOTO (n = 1) and significant pulmonary regurgitation (PR) (n = 1) at the last follow-up. On Cox regression, neonatal repair (hazard ratio [HR], 5.12, P = 0.02) and a higher P
