Esophageal Atresia in Asia: Regional Disparities in Incidence, Congenital Anomalies, Mortality, and Morbidity - A Systematic Narrative Review.
Review in Journal of Indian Association of Pediatric Surgeons. 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
Background: Esophageal atresia (EA), with or without tracheoesophageal fistula, remains associated with substantial early mortality and long-term morbidity. Reported incidence and outcomes vary across Asia, but interpretation is complicated by differences in case capture, referral pathways, diagnostic capacity, and neonatal intensive care availability. Methods: We performed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020-aligned systematic narrative review of observational studies from Asian countries published up to March 2024 (PubMed and Google Scholar). Studies reporting incidence, associated anomalies, morbidity, or mortality were included. Findings were synthesized descriptively and presented stratified by study base (population-based vs. hospital-based) and resource setting (World Bank income proxy). Risk of bias was assessed using a generic domain-based framework (D1-D6). Results: Thirty-four studies (3304 infants) were included. Six population-based studies reported incidence ranging from 6.17 to 20.30 per 100,000 live births. Hospital-based reports documented 921 associated anomalies, most commonly gastrointestinal (36%) and cardiovascular (27%). Mortality across 19 cohorts ranged from 2% to 83%. Morbidity profiles differed by setting: in higher-resource cohorts, reported events were dominated by gastroesophageal reflux and anastomotic stricture, whereas in lower-resource cohorts, septicemia (47% of events) and wound infection (10%) were prominent. Conclusion: EA incidence in Asia is within international ranges, but published outcomes vary widely and should be interpreted descriptively given referral and ascertainment differences, variable anomaly detection, heterogeneous definitions, and limited follow-up. Priorities include strengthening prenatal detection and referral, improving neonatal stabilization and safe transport, standardizing perioperative care with infection prevention, and establishing feasible long-term follow-up supported by a pragmatic action framework.
