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

Flamboyant sexual ornaments serve as conspicuous visual signals optimized to the visual receptors and perception of potential mates. While numerous studies have explored the mechanisms and functions of body coloration as a sexual signal, the role of another essential property of light-polarization-remains largely unexplored. Specifically, the question of whether and how polarization signals achieve high conspicuousness under sexual selection, including their visibility and associated behavioral and morphological adaptations, has yet to be thoroughly investigated. Here, we identified a strikingly conspicuous polarization signal used specifically during courtship in the cuttlefish
