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

Biogenic guanine crystals found in various aquatic and terrestrial animals, show unique optical properties that include structural coloration as well as reflectance and have intrigued researchers for over a century. Besides the highly reflective nature of these organic crystals, guanine-rich parts of certain organisms (fishes, geckos, etc.) show emission in the visible region upon UV light exposure. This fluorescence is used by these organisms for intra-specific signaling. However, there is no available literature regarding the occurrence and origin of visible light emission in guanine crystals. Earlier reports suggest that guanine, when excited at its absorption maxima (254 nm), emit in the UV region (λ
