1 · What the graph read from it

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.

2 · The registry

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

Anophthalmia is defined as a complete absence of one eye or both the eyes, while microphthalmia represents the presence of a small eye within the orbit. The estimated birth prevalence for anophthalmia is approximately 3 per 100000 live births, and for microphthalmia, it is around 14 per 100000 live births. However, combined evidence suggests that the prevalence of these malformations could be as high as 30 per 100000 individuals. Microphthalmia is reported to occur in 3.2% to 11.2% of blind children. Anophthalmia and microphthalmia (A/M) are part of a phenotypic spectrum alongside ocular coloboma, hypothesized to share a common genetic basis. Both A/M can occur in isolation or as part of a syndrome. Their complex etiology involves chromosomal aberrations, monogenic inheritance pattern, and the contribution of environmental factors such as gestational-acquired infections, maternal vitamin A deficiency (VAD), exposure to X-rays, solvent misuse, and thalidomide exposure. A/M exhibit significant clinical and genetic heterogeneity with over 90 genes identified so far. Familial cases of A/M have a complex genetic basis, including all Mendelian modes of inheritance,
