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
introductionThis study aims to systematically describe eye malformations and correlate these with extraocular findings. Based on these findings, we propose a protocol for ultrasound evaluation of the fetal eye. MATERIAL AND
methodsIn this multicentric retrospective cohort study, 264 fetuses with ocular malformations from two tertiary referral centers for prenatal medicine were analyzed. Anophthalmia, microphthalmia, exophthalmos, hyper- or hypotelorism, cataract, aphakia, cyclopia, and retinal detachment were assessed, and their association with extraocular findings and genetic changes was investigated.
resultsThe majority of the cases (99.2%) were non-isolated and presented further extraocular findings. Most commonly, the brain and central nervous system (65.9%), the limbs and the heart (46.6% each) and the cranial anatomy (41.2%) were affected. Significant associations were found between exophthalmos and anomalies of the fetal skeletal system (OR = 4.8, 95% CI 1.6-14) and cranial malformations (OR = 3.3, 95% CI 1.5-7.4). Hypotelorism showed an increased risk of cardiac anomalies (OR = 1.8, 95% CI 1.1-3.5) and brain malformations (OR = 2.16, 95% CI 1.2-4.1), with holoprosencephaly being the most common one. Fetuses with microphthalmia were more likely to have anomalies in the renal system (OR = 2.3, 95% CI 1.2-4.3). In 51.4% of the cases, a genetic aberration could be found, among them most frequently trisomy 13.
conclusionsThere is a significant association between specific fetal eye anomalies and certain extraocular anomalies, as well as genetic changes. Systematic evaluation of the eye using the proposed protocol is simple to learn and highly reproducible and could help to concentrate diagnosis on a certain group of malformations. Data from this study could help to develop targeted diagnostic molecular tools.
