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

Butterfly wing vivid colors arise from light reflecting off cuticular scales, whose architecture consists of longitudinal ridges and transverse crossribs connected to a lower lamina by trabeculae. While the lower lamina's reflective properties are known in simpler scales, the upper surface's optical characteristics have only been thoroughly investigated in the case of modified ridges. This study examines how the lower lamina and the upper surface contribute to hue, brightness, and saturation across species. In
