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

backgroundIn cases of distal radius fractures information about the regional distribution of cancellous bone is essential for adequate fixation of osteosynthesis material. MATERIALS AND

methodsUsing quantitative computed tomography (qCT) measurements 12 distal radii were divided into 2 groups (good and bad bone quality). High-resolution CT scans were obtained at 13 locations (1-40 mm distant from radial styloid processes). The resulting cross-sections were divided into 4 quadrants and the cancellous bone density was assessed in each of them.

resultsIn both groups regional cancellous bone density was highest immediately beneath the joint surface and decreased towards the metaphyseal region. Comparing the radial with the ulnar quadrants significant differences were found between distances of 4 mm and 12 mm from the joint surface in both groups. The comparison of the palmar and the dorsal quadrants resulted in an almost identical cancellous bone distribution.

conclusionIn osteoporotic distal radii cancellous bone density decrease occurs homogeneously in all regions and is least pronounced beneath the joint surface. Comparing the regional cancellous bone density (radial versus ulnar and palmar versus dorsal) significant differences were mainly found near the joint surface in both groups.
