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 heterogeneous connective tissue disorder characterized by increased bone fragility and a series of extraskeletal manifestations. Approximately 90 % of OI cases are caused by type I collagen variants encoded by the collagen type I alpha 1 (COL1A1) or type I alpha 2 (COL1A2) gene. Lumbar Scheuermann's disease is an atypical type of Scheuermann's disease accompanied by Schmorl's nodes and irregular endplates but without pronounced kyphosis. Although the etiology of Scheuermann's disease is unclear, genetic and environmental factors are likely. CASE PRESENTATION: Here, we report a 32-year-old male patient who experienced multiple brittle fractures. Gene sequencing revealed a heterozygous mutation, c.4048G > A (p.G1350S), in the COL1A2 gene, and the patient was diagnosed with OI. Magnetic resonance imaging of his thoracolumbar spine revealed multiple Schmorl's nodes.

conclusionsThis is the first reported case of OI coexisting with the spinal presentation of Scheuermann's disease. It is speculated that the COL1A2 gene mutation might be an underlying novel genetic cause of Scheuermann's disease. In conclusion, this case demonstrates the relationship between Scheuermann's disease and OI for the first time and enriches the genotype-phenotype spectrum of OI.
