Delayed macular development in preterm infants with spontaneously regressed retinopathy of prematurity.
Observational study in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
purposeTo evaluate the macular development in preterm infants with spontaneously regressed retinopathy of prematurity (ROP) utilizing handheld spectral domain optical coherence tomography (SD-OCT) during the early postnatal period.
designA cross-sectional observational study.
methodsUsing handheld SD-OCT, OCT images were acquired in non-sedated infants ages about 37 weeks(w) post-menstrual-age (PMA = gestational age in weeks + chronological age). Central foveal thickness (CFT), mean parafoveal thickness (PT, mean of the temporal and nasal-lateral retinal thickness 1000 μm from the foveal center), the thickness of inner retina layers (IRL) and outer retina layers (ORL) of the foveal center and parafoveal, the depth of the macular fovea (FD), and the angle of the macular fovea (FA) were measured and analyzed.
resultsIn contrast to the infants without ROP (group 1), OCT images of the infants with spontaneously regressed ROP (group 2) were more immature. The FD of Group 2 was shallower than Group 1 (P < 0.05); CFT and the foveal center IRL (FIRL) of Group 2 were thicker than Group 1 (P < 0.05); conversely, PT and the mean parafoveal IRL (PIRL) of Group 2 were thinner than Group 1 (P < 0.05); FA of Group 2 was bigger than Group 1 (P < 0.05); however, there was no significant difference in the foveal center ORL (FORL) and the mean parafoveal ORL (PORL) between Groups 1 and 2 (P > 0.05). Furthermore, in preterm infants, ROP was moderately correlated with FD, CFT, PT, FIRL, and PIRL (P < 0.05).
conclusionsThe spontaneously regressed ROP resulted in immature macular development in the early postnatal period. The inner retinal layers mainly contribute to this but not the outer retinal layers, indicating that the macular fovea's inner and outer retina layers developed asynchronously. ROP is an influential factor in macular development and maturation. This may be associated with the higher probability of visual impairment in children with a history of spontaneous regression of ROP at a prior time.
