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: Osteogenesis imperfecta (OI) comprises a heterogeneous group of skeletal dysplasias characterized mainly by bone fragility and propensity to fractures. The most common forms include classic types I, II, III, and IV, according to the classification of Sillence, caused by variants in the Case Presentation: Six individuals (1M:5F), aged 8 months to 34 years at their first consultation, were enrolled. All were clinically classified as OI type I due to the presence of osteopenia associated with blue sclerae and bone fractures; four presented with short stature, two with hearing loss, and one with fragile teeth; molecular testing confirmed that all presented with heterozygous pathogenic or likely pathogenic variants in the Conclusion: Bathrocephaly and serpentine fibula are rarely reported in classical OI types and are more frequently associated with other skeletal dysplasias, such as Hajdu-Cheney syndrome. This case report highlights the importance of recognizing underrated manifestations in OI and underscores the need for molecular confirmation.
