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

This study employs synchrotron-based FTIR microspectroscopy and principal component analysis (PCA) to investigate natural dyes in wool textiles from the Chehrabad salt mine (Iran), dated to the Sassanid period (220-390 A.D.). We identified indigotin (blue), tannic acid (brown), quercetin and apigenin (yellow), and alizarin and carminic acid (red), with the absence of luteolin suggesting alternative native dye sources. Spectral analysis revealed dye-wool lipid interactions in the Amide and lipid regions, providing insights into Sassanid dyeing technologies and regional dye variations. Synchrotron FTIR proves a powerful non-destructive tool for archaeological textile analysis.
