Prevalence of Congenital Ocular Anomalies in 15 Countries of Europe: Results From the Medikeye Study.

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
backgroundCongenital ocular anomalies (COA) are among the most common causes of visual impairment in children in high-income countries. The aim of the study is to describe the prevalence of the various COA recorded in European population-based registries of CA (EUROCAT) participating in the EUROmediCAT consortium.
methodsData from 19 EUROmediCAT registries and one healthcare database (EFEMERIS) were included in this descriptive epidemiological study. Cases of COA included live births, FD from 20 weeks gestational age (GA), and termination of pregnancy for fetal anomaly.
resultsThe prevalence of total COA was 3.47/10,000 births (95% CI [3.61-3.82]), ranging from 1.41 to 13.46/10,000 depending on the registry. Among COA cases, congenital lens anomalies were the most frequent anomalies (31%), of which over half were single ocular anomalies (presenting with only one ocular anomaly). An/microphthalmia was the second most frequent COA (24%) of which three-quarters were multiply malformed (associated to extraocular major anomalies). Among single COA cases, 58 were prenatally diagnosed (4%), of which, 58% were diagnosed in the second trimester. Known genetic causes of COA explained 2.5%-25% of COA depending on their class.
conclusionsThis is the first European study describing COA. The detailed prevalence data offered in this study could improve screening and early diagnosis of different classes of COA. As COA are rare, epidemiological surveillance of large populations and accurate clinical descriptions are essential.
