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

Introduction: Kniest dysplasia is a severe form of type II collagenopathy caused by mutations in collagen II alpha 1 chain ( Case Presentation: We describe a female patient aged 39 years with difficulty in walking, back pain, and limited movement of the lower extremities. She had experienced neck pain during adolescence; however, it gradually decreased with age. She also showed markedly short stature (-4.37 SD), cleft palate, cataract, retinal detachment, and serous otitis media. Radiographic analyses revealed epiphyseal enlargement of the longitudinal bones, kyphoscoliosis, and flat vertebrae in the thoracolumbar spine. The cervical spinal bodies were fused but not at the age of 19 years. Genetic analysis revealed a novel heterozygous mutation, c.1266+2T>A, in intron 20 of Discussion: The diagnosis of Kniest dysplasia is sometimes difficult based on clinical findings in adulthood owing to progressive skeletal changes. The current novel splice mutation in
