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

Spodumene, a lithium-rich pyroxene mineral, exhibits a wide range of colors and distinctive luminescent properties, yet the mechanisms underlying its coloration and fluorescence remain incompletely understood. In this study, twelve natural spodumene samples of varying colors (purple, yellow, green, and nearly colorless) were systematically analyzed by modern testing technology. Color variation of the sample is primarily controlled by the Mn/Fe ratio, with purple tones corresponding to Mn/Fe > 1, yellow to green to Mn/Fe < 1, and colorless samples showing negligible Mn and Fe content. All samples exhibited two emission centers near 420 nm and 600 nm, attributed to lattice defects and the
