Incidence and risk factors of retinopathy of prematurity in artificial reproductive technology conceived preterm infants in China.
Article in International journal of retina and vitreous, 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
backgroundTo evaluate the incidence and associated risk factors of retinopathy of prematurity (ROP) in preterm infants conceived through assisted reproductive technology (ART) in China.
methodsWe conducted a retrospective analysis of preterm infants who were hospitalized between August 2019 and December 2024. Infants were divided into two groups based on mode of conception: ART-conceived and naturally conceived. The incidence of ROP was compared between the groups. Clinical data were collected for both the infants and their mothers.
resultsA total of 1,019 preterm infants were included, comprising 195 ART-conceived and 824 naturally conceived infants. ROP was diagnosed in 33 ART-conceived (16.9%) and 136 naturally conceived infants (16.5%), with no statistically significant difference between the two groups (P = 0.888). Similarly, no significant difference was observed in ROP staging (P = 0.228). Multivariable logistic regression analysis showed that, in the ART-conceived group, greater gestational age (OR: 0.618) and a history of antenatal corticosteroid use (OR: 0.278) were protective factors, whereas apnea of prematurity (OR: 3.170) increased the risk of ROP. Similarly, in the naturally conceived group, greater gestational age (OR: 0.840) was also a protective factor, while apnea of prematurity (OR: 1.666) increased the risk of ROP.
conclusionThe incidence of ROP did not differ significantly between ART-conceived and naturally conceived preterm infants. In ART-conceived infants, higher gestational age and a history of antenatal corticosteroid use were protective factors, whereas apnea of prematurity increased the risk of ROP.
