Prevalence and risk factors for retinopathy of prematurity in preterm infants at a Brazilian tertiary hospital: a cross-sectional study.
Observational study in BMC pediatrics, 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 estimate the prevalence and factors associated with retinopathy of prematurity (ROP) in preterm infants at a tertiary hospital in Central-West Brazil.
methodsThis retrospective, observational cohort study analyzed the medical records of neonates with a gestational age (GA) ≤ 32 weeks and/or birth weight ≤ 1,500 g assisted between March 2022 and February 2024. Statistical analyses included the Mann-Whitney U test, Pearson's chi-square test, and Fisher's exact test, followed by multivariable logistic regression with Least Absolute Shrinkage and Selection Operator (LASSO) penalization.
resultsAmong the 208 eligible preterm infants included in the study, 40 developed ROP, corresponding to a prevalence of 19.2%, where stage 2 was the most frequent, 17 (42.5%). Treatment was required in 25% of ROP cases, with no progression to stages 4-5. ROP was more frequent among extremely preterm infants and those with extremely low birth weight (p < 0.001). In the adjusted analysis, extreme prematurity and female sex were independently associated with ROP, whereas jaundice was inversely associated with the outcome.
conclusionsExtreme prematurity and female sex were independently associated with ROP in this cohort of preterm infants, whereas jaundice showed an inverse association with the outcome. These findings reinforce the multifactorial nature of ROP and the importance of continuous surveillance in high-risk preterm newborns.
