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

BackgroundOsteogenesis imperfecta (OI) is a heritable bone fragility disorder usually caused by dominant variants in COL1A1 or COL1A2 genes. Over the last few years, 17 genes including 12 autosomal recessive and five autosomal dominant forms of OI, involved in various aspects of bone formation, have been identified.MethodsWhole-exome sequencing followed by conventional Sanger sequencing was performed in a single affected individual (IV-3) in a family.ResultsHere, we report the clinical and genetic characterization of OI type 3 in a consanguineous family with four affected members. Clinical examinations revealed low bone density, short stature, severe vertebral compression fractures, and multiple long bone fractures in the affected members. Exome sequencing revealed a biallelic pathogenic splice acceptor site variant (c.359-3C>G) in a wingless-type mouse mammary tumor virus integration site family 1 (WNT1) gene located on chromosome 12q13.12.ConclusionWe report a biallelic splice site variant underlying OI type 3 and the first case from the Pakistani population.
