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 Surinam toad (Pipa pipa) is a fully aquatic, tongueless pipid frog that captures prey using rapid suction feeding coordinated by the forelimbs. The digit tips bear distinctive lobed structures whose function has been unknown. Here we characterize the morphology, mechanical sensitivity, peripheral innervation, central representation, and behavioral function of these digit tip lobes using scanning electron microscopy, von Frey threshold measurements, in vivo electrophysiology of the brachial nerve and optic tectum, and high-speed video analysis (1000 fps). SEM reveals a progressive quadrification yielding 128 terminal lobules per frog, bearing dome-shaped papillae at 142 ± 18/mm
