Oxygen therapy-related risk factors for aggressive retinopathy of prematurity in low-risk preterm neonates.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAggressive retinopathy of prematurity (A-ROP) poses a significant risk for visual impairment in preterm neonates, including those considered at low risk for ROP. Nonetheless, factors influencing A-ROP occurrence in low-risk preterm neonates remain underexplored. We aimed to identify oxygen therapy-related factors associated with A-ROP in this population.
methodsThis retrospective case-control study included low-risk preterm neonates (gestational age ≥30 weeks and birth weight ≥1 kg) treated for ROP between January 2005 and May 2023 at two Korean hospitals. Patients were divided into A-ROP and staged ROP groups, and oxygen therapy-related factors were analyzed using logistic regression.
resultsOf the 99 neonates included, 72% were diagnosed with A-ROP. No significant between-group differences were observed in the total duration of oxygen therapy or its delivery methods, except for non-invasive positive ventilation. Mean partial pressure of oxygen (odds ratio [OR], 0.94; 95% confidence interval [CI], 0.89-0.99) and its fluctuation (OR, 1.09; 95% CI, 1.03-1.15) were significant risk factors for A-ROP, with cutoff values of <52.8% and >82.3%, respectively.
conclusionMaintaining stable oxygen levels while avoiding hypoxia may help reduce the risk for A-ROP in low-risk neonates requiring ROP treatment. These findings may help refine oxygen therapy guidelines in neonatal care to improve A-ROP prevention in this population. IMPACT STATEMENT: Aggressive retinopathy of prematurity (A-ROP) can significantly threaten vision, even in preterm neonates considered at low risk for ROP. The contributing factors to A-ROP in this low-risk population have been insufficiently investigated. This study is the first to identify peripheral oxygen levels and their fluctuations as significant factors associated with A-ROP development in low-risk preterm neonates requiring treatment. These findings highlight the importance of maintaining stable oxygenation and preventing hypoxia to reduce the risk of A-ROP in this population.
