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

purposeTo identify mutations in a Chinese family with congenital cataract and microcornea.

methodsDetailed family history and clinical data were recorded. Genomic DNA was extracted from leukocytes of venous blood of the patients and noncarriers in this family along with 100 normal individuals. All six exons of crystallin, beta A4 gene (CRYBA4) were amplified by PCR methods and direct sequencing.

resultsWe identified a c.225G>T sequence change that led to an amino acid substitution G64W in the CRYBA4-induced protein in two patients of this family; this nucleotide substitution was not detected in the other individuals.

conclusionsA novel missense mutation in CRYBA4 was identified in our study. It expands the mutation spectrum of CRYBA4 and provides useful information to the study of molecular pathogenesis of cataract and microcornea.
