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

backgroundDaily residual limb fluid volume fluctuation is thought to be a driving factor behind prosthetic socket fit deterioration among people with lower limb amputation. Expanding the number and type of strategies available to manage daily residual limb fluid volume changes may improve socket fit.

methodsTo investigate the effects of partial-doff frequency on residual limb fluid volume, participants completed two controlled laboratory sessions that differed in the number of times participants sat and partially doffed their prosthesis. Transtibial prosthesis users were recruited, fitted with a custom limb fluid volume monitoring device and a socket release-relock mechanism, and asked to complete a series of low- and high-activity ambulation bouts that mimicked daily prosthesis use.

findingsMean limb fluid volume measures from the anterior compartment of the residual limb were significantly different between the one- and three-partial doff experimental protocols (-5.8 % and -2.1 % fluid volume, respectively, P < 0.01). The posterior compartment limb fluid volume, locking pin depth, locking pin magnitude of movement, anterior distal limb position depth, and anterior distal limb position total movement did not differ significantly between the two conditions.

interpretationPartial doffing may offer prosthesis users an alternative means to accommodate limb fluid volume changes. More frequent partial doffing appears to better mitigate limb fluid volume loss when compared to less frequent partial doffing.
