Rethinking timing: Outcomes of late versus early surgical repair of complete atrioventricular septal defect in a resource-limited setting.
Article in JTCVS open, 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
Objective: Complete atrioventricular septal defect (CAVSD) repair is ideally performed within the first 6 months of life; however, in resource-limited settings, access barriers often delay surgery We compared outcomes between early (<6 months) and late (≥6 months) surgical repair at a single reference center in Colombia. Methods: A retrospective cohort of 111 consecutive patients (2012-2022) undergoing primary CAVSD repair was analyzed. Patients were divided into early (n = 22) and late (n = 89) groups. Preoperative, intraoperative, and postoperative variables-including operative mortality, survival, and freedom from left atrioventricular valve (LAVV) reintervention-were compared using χ Results: Median age at surgery was 4.9 months (interquartile range, 4.5-5.4) for early versus 8.5 months (interquartile range, 7.2-14.3) for late repair. Trisomy 21 was present in 83.8%. The early group had greater preoperative oxygen saturation ( Conclusions: In this cohort, later CAVSD repair yielded operative mortality and medium-term outcomes comparable with early repair despite less-favorable preoperative profiles. These findings may support flexible surgical timing in resource-limited settings with robust perioperative care and follow-up.
