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

Birds can experience localized forces against their bodies due to impact against solid objects (like a branch or another bird) or water (during plunge-dives or landings). In this study, we hypothesize that densely packed contour feathers around the bird body would spread localized impact force while diving and maintaining plumage integrity. To test the hypothesis, we performed experiments with individual feathers and elastic beams, and developed a theoretical model to determine the response of feathers during the dive. First, we used a micro computed tomography scanner to characterize the internal structure of the contour feather from a northern gannet and calculate Young's modulus of feathers sampled from different parts of the body. This value was found to be of the order of 10
