Ocular Biometry in Preterm Newborns in the Neonatal Intensive Care Unit Environment of a Referral Hospital.

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
Purpose: The purpose is to document ocular growth using ultrasound biometry measurements in conditions of prematurity with or without retinopathy. Design: An observational prospective study. Subjects: One hundred twenty eyes of preterm infants in the neonatal intensive care unit. Methods: Follow-up every 2 weeks until 6 weeks postnatally. Inclusion criteria <1500 g or 32 gestational weeks/exclusion criteria >1500 g or 32 gestational weeks. Main Outcome Measures: Ocular biometric parameters were evaluated using B-scan ultrasound (7.5-15 MHz, Mylab Esaote). These included anterior chamber depth, anterior-posterior lens diameter (lens thickness), vitreous chamber depth, and axial length. Additional evaluation parameters included refraction using retinoscopy to determine the refractive error, indirect ophthalmoscopy with 28 diopter lenses, and pediatric biometric parameters recorded in the medical record. Results: Total number: 120 eyes, 60 patients (29 females; 31 males); retinopathy of prematurity (ROP) number: 48 eyes, 24 patients (13 females; 11 males) were included, and the right eye was analyzed. Through repeated analysis of variance, a statistically significant effect on ROP did not differ significantly from any of the measures evaluated by the rest of the group. The biometric parameter showed a positive correlation relationship with gestational age. However, the refractive spherical was observed in the opposite behavior. The lens thickness and spherical equivalent were not shown. There was a significant correlation with gestational age; only the spherical equivalent significantly correlated with the Z-weight score for gestational age. Conclusions: In this study, it was possible to document the pattern of ocular growth in preterm infants with the progression of gestational age without differentiation between the groups of preterm infants (with and without ROP).
