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

The morphology of peripheral nerves sampled at the time of nerve transfer surgery was directly assessed in participants within 15 months of their SCI. Fresh nerve samples were fixed in glutaraldehyde, processed and embedded in Araldite Epon. Light and electron microscopy was used to conduct a qualitative analysis of morphology and a quantitative morphometric analysis of axon, fibre and myelin areas and diameters and g-ratios. Over two-thirds of both donor and recipient nerves showed abnormalities that differed in appearance and aetiology. These included myelin thickening and folding (tomacula), demyelination, reduced density of large, myelinated axons, oedematous endoneurium, evidence of compression, and thickened epineurium and perineurium. Morphometric analysis showed differences in axon density and myelination in the sampled nerves, with substantial nerve fibre loss in teres minor and posterior axillary nerves, and increased myelin area in the other sampled nerves. Mean (SD) myelin area ranged from 26.23 (13.86) to 66.02 (32.14) µm
