Subtypes and corneal astigmatism in pediatric persistent fetal vasculature.

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
aimTo characterize the distribution of persistent fetal vasculature (PFV) subtypes and to evaluate corneal astigmatism (CA) in children with unilateral PFV.
methodsThe medical records of patients diagnosed with PFV between January 2014 and August 2021 were retrospectively reviewed. Corneal keratometry parameters were measured using IOLMaster or a handheld keratometer. Differences in CA between the affected and fellow eyes were analyzed in 52 unilateral PFV patients with available examination data.
resultsTotally 133 patients diagnosed with PFV were retrospectively reviewed. The male-to-female ratio was 73/60. Median age at surgery was 38.03mo (interquartile range 58.27mo). Among the PFV patients, 32 (24.06%) had anterior PFV, 2 (1.50%) had posterior PFV, and 99 (74.44%) had combined anterior-posterior PFV. Mild combined PFV was the most common subtype. In unilateral PFV cases, the mean CA in the affected eye was 2.29±1.11 D, and 59.62% (31 eyes) had CA≥2.0 D. The mean CA in the affected eyes was significantly higher than in the fellow eyes (1.37±0.77 D;
conclusionIn children with unilateral PFV, CA is significantly higher in the affected eyes than in the fellow eyes, and the steepest corneal meridian was predominantly oriented vertically.
