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

introductionEccentricity Index is an echocardiographic predictor of disease severity in children with pulmonary arterial hypertension (PAH). Its utility after atrioventricular septal defect (AVSD) repair remains unclear due to surgical manipulation of the ventricular septum. We evaluated end-systolic (EIs) and maximal (EIm) as predictors of hemodynamics post-AVSD repair.

methodsCohort 1 was 89 children, 5-24 months after complete AVSD repair, and similarly aged controls. Subgroups of those with (+) and without (-) PAH were based on other echocardiographic markers of PAH. Cohort 2 was 20 children who underwent cardiac catheterization after AVSD repair. EIs and EIm were calculated as the ratio of the left ventricular diameter parallel to the septum divided by the perpendicular diameter measured at end systole and maximal post-systolic flattening, respectively.

resultsIn Cohort 1, EIs and EIm in AVSD cases were greater than in controls. Both were highest in PAH(+) patients, followed by PAH(-), followed by controls. EIs predicted echo-estimated right ventricular systolic pressure, while EIm did not. In Cohort 2, EIs and EIm predicted RVSP ≥ 35 mmHg, while only EIs predicted PVRi ≥3 Wu*m

conclusionsAfter AVSD repair, EIs and EIm are elevated compared to those of otherwise healthy children. However, significant elevation (Eis > 1.28) may still be useful to differentiate those with and without PAH. A multiparametric approach may be needed for borderline EIs (1.09-1.28). These findings support EI as a non-invasive screening tool to identify PAH in children after AVSD repair.
