The association of various obstetric and perinatal factors with retinopathy of prematurity.
Article in International ophthalmology, 2022. 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
purposeTo analyze the effects of various obstetric and perinatal factors on the severity of retinopathy of prematurity (ROP).
methodsInfants born at ≤ 32 weeks of gestation, with less than 1500 g gestational weight and having at least stage 1 ROP, were reviewed. Group1A included treatment-requiring ROP (TR-ROP), and group 2A included the remaining patients not requiring treatment. Group 1B included stage 3 ROP cases, and group 2B included the remaining stage 2 or 1 ROP cases. Group 1C included cases with zone III disease, and group 2C the remaining. The control group (group C) was composed of premature infants without ROP. The multiple comparisons were made among groups 1A, 2A, and C; 1B, 2B, and C; 1C, 2C, and C.
resultsA total of 311 infants were included. Group 1A included 34 cases, group 1B 60, group 1C 51, and group C 98. Antenatal steroid administration, gestational diabetes mellitus (GDM), gestational weight (GW), gestational age (GA), sepsis, continuous positive airway pressure (CPAP) time, and invasive mechanical ventilation (MV) time were associated with TR-ROP, stage 3 ROP, and zone I, and II disease (p < 0.05). Pregestational diabetes mellitus (DM) was only associated with stage 3 ROP (p = 0.031). Gestational hypertension was only associated with zone I and II disease (p = 0.034). The use of low-molecular-weight heparin may be protective against stage 3 disease (p = 0.031).
conclusionAntenatal steroid administration, GDM, GW, GA, sepsis, CPAP time, and invasive MV time were risk factors for TR-ROP and stage 3 ROP, while pregestational DM was only associated with stage 3 ROP.
