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

We report a rare case of capitate osteonecrosis in a 51-year-old woman with thalassemia presenting with persistent wrist pain. Imaging findings were consistent with osteonecrosis of the capitate, and the patient underwent surgical treatment with a vascularized bone graft from the second metacarpal and cancellous bone graft from the iliac crest. Histopathological examination confirmed ischemic osteonecrosis. At 15 months after surgery, clinical improvement was limited; however, magnetic resonance imaging demonstrated preservation of capitate morphology and reduced signal abnormalities. Capitate osteonecrosis in patients with thalassemia is extremely rare but should be considered in the differential diagnosis of wrist pain. Early recognition may facilitate timely intervention and help prevent disease progression.
