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 conducted a systematic review of the definition of a scaphoid fracture on MRI scans, examining 58 studies of patients with suspected scaphoid fractures. Nearly half the studies did not report any definition or measurement of fracture. Among those that did, 29 out of 33 studies (88%) described a linear fracture shape, 13 out of 33 studies (39%) reported the extent of the fracture across the scaphoid and none specified the fracture line orientation. Of the 25 studies describing fractures using at least one of the shape and extent groupings, 12 (48%) regarded a linear signal through the cortex as a fracture, five (20%) regarded a linear intramedullary signal in isolation as a fracture and eight (32%) regarded a diffuse intramedullary signal in isolation as a fracture. This review highlights the need for a consensus definition of scaphoid fractures on MRI scans to assess the reliability and diagnostic performance of MRI scans for diagnosing true scaphoid fractures, as well as their potential harms and benefits.
