Gestational Age-Specific Prevalence of Retinopathy of Prematurity in Very Preterm Infants: An Exploratory Meta-Analysis.
Synthesis in Acta paediatrica (Oslo, Norway : 1992), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
aimTo evaluate whether Retinopathy of Prematurity (ROP) research cohorts should be defined exclusively by gestational age (GA) thresholds rather than the current standard of combining GA with birth weight (BW).
methodsLiterature search of publications between 1971 and 2024, and data extraction using predefined search terms and inclusion criteria.
resultsROP prevalence changes notably at around 28 weeks GA, decreasing appreciably at older gestational ages. Including BW alongside GA (as is done in some ROP screening guidelines) affects the variability of ROP prevalence data and may obscure the true population-level association between GA and ROP severity.
conclusionClinical study populations for ROP research should be defined by GA thresholds only, without additional BW inclusion criteria.
