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

backgroundMany techniques have been used to treat palmar hyperhidrosis. Compensatory sweating is a difficult adverse effect. Clipping has been proposed because of its supposed reversibility when clips are removed at a later date. The primary aims of this article are to investigate the neuronal lesion of the sympathetic chain caused by clipping and to study the possibility of regeneration after removal of the clips.

methodsWe performed an experimental study at the Minimally Invasive Surgery Centre Jesus Uson in Caceres (Spain). We used a swine model, performing clipping, unclipping, and extirpation of different segments of sympathetic chain with clips and after clip removal, following a chronogram of 10, 20, and 30 days. Pathologic studies of specimens and statistics were done at the University of Seville.

resultsTen days after clipping, all sympathetic chains displayed evident Wallerian degeneration. Twenty days after clipping, Wallerian degeneration of myelinated fibers was more widespread and also more striking. Thirty days after clipping, a very marked macrophagic reaction was visible, with multiple signs of phagocytosis of myelin debris. By 30 days post operation and 20 days after clip removal, a few residual myelin and amyelinated fibers were visible. These findings suggest that axon regeneration is not possible.

conclusionsThere are Wallerian degeneration and axon loss 10 days after clipping. The almost total absence of myelinated and amyelinated fibers following clip removal suggests that there was no nerve regeneration, and that therefore clipping cannot be considered a reversible technique.
