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

In cases of severe damage to the extremities, the function and structure of compromised biological tissues must be replaced. If biological reconstruction using autologous tissue is not feasible, amputation and replacement with a synthetic prosthesis is often the next best option. Currently, the synthetic materials available for prostheses are limited, especially in their ability to restore skin sensation. Here we show a biosynthetic prosthesis that combines the versatility of titanium with the rich sensory capabilities of biological skin, to both increase movement and restore sensation to an amputated thumb. The prosthesis recreates opposition pinch by linking motion of the prosthetic joint to that of the residual biological joint. The device is enclosed in neurotized skin from the patient's own body, providing natural sensation. We validated the biosynthetic thumb's ability to reproduce opposition pinch on the benchtop and in a cadaver, and showed One Sentence Summary: A prosthetic thumb made up of a titanium mechanism and living skin can restore opposition pinch and touch sensation following thumb amputation.
