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 minerals such as shells contain trace amounts of biological polyenes derived from carotenoids, which have attracted considerable attention in biology, earth science, environmental science, and materials science. Moreover, the recent issue of fraudulent labeling of edible shellfish origins underscores the need for reliable, nondestructive methods to identify species and habitats. Here, we applied resonance Raman spectroscopy to nondestructively detect carotenoid-derived polyenes (biological polyenes) in various shells differing in species and growing environments. We focused on the peak positions and full width at half-maximum (FWHM) of the bands at around 1500 and 1120 cm
