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

backgroundTo elucidate the genetic underpinnings of short stature in a familial cohort of five individuals.

methodsA family with a history of short stature from Zhongnan Hospital of Wuhan University was the subject of this study. Peripheral blood samples were collected from family members for whole exome sequencing and Sanger sequencing to identify genetic anomalies.

resultsThe male proband, aged 3 years and 10 months, had significant growth retardation, with a height of 91 cm (< 3rd percentile) and a weight of 13 kg (< 3rd percentile). Whole exome sequencing identified a missense mutation in the COL1A2 gene (c.577G>A, p.Gly193Ser) with maternal inheritance. Sanger sequencing confirmed this mutation in the mother and half-sister. According to American College of Medical Genetics and Genomics (ACMG) guidelines, this variant was classified as likely pathogenic. Additionally, a heterozygous mutation in the GH1 gene (c.291+1G>A) was detected in the father and grandfather, contributing to the familial short stature phenotype.

conclusionIn this family, we identified that variants in the COL1A2 and the GH1 can each cause short stature. This reflects both the genetic consistency and complexity of short stature, which is highly dependent on comprehensive genetic testing.
