Congenital cataract in children: Age at surgery and diagnosis-treatment interval in the Brazilian Unified Health System in Salvador (BA), Brazil.
Observational study in Revista paulista de pediatria : orgao oficial da Sociedade de Pediatria de Sao Paulo, 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
objectiveTo determine the age at first congenital cataract surgery and the diagnosis-to-treatment interval at a specialized service in Salvador, Brazil, quantifying treatment delay and characterizing the clinical-epidemiological profile of the population.
methodsRetrospective, observational case series with an exploratory analytical component, including pediatric patients who underwent congenital cataract surgery through the Brazilian Unified Health System between 2015 and 2024. The primary outcomes were age at first surgery and the diagnosis-to-treatment interval; as a secondary, exploratory aim, factors associated with surgical age were examined. Student's t-test, the Mann-Whitney U test, and linear regression were used, with estimates reported as coefficients and 95% confidence intervals - 95%CIs (p<0.05).
resultsA total of 187 patients (274 eyes) were included, predominantly male (60.4%) and bilateral (54.5%). The median age at surgery was four years (interquartile range [IQR] 2.0-6.0), and no child was operated on within the recommended window; only 13 (7.0%) underwent surgery before one year of age. The diagnosis-to-treatment interval was adequate in 48.1% and delayed in 51.9%. In the exploratory adjusted model, no variable was independently associated with surgical age (adjusted R2=0.029). The median remained 4.0 years even in the absolute-surgical-indication subgroup, indicating that greater clinical severity did not translate into earlier surgery.
conclusionsSurgery occurred well beyond the recommended window. As the in-hospital interval was relatively efficient, the delay appears to lie upstream of referral, reinforcing the need to strengthen neonatal screening and early detection in primary care.
