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

Textile-derived microplastics (MPs), particularly polyethylene terephthalate (PET) microfibers from infant garments, are an emerging concern due to potential early-life exposure and the vulnerability of infant physiological systems. However, existing analytical methods are often limited by complexity or poor suitability for larger, irregular textile fibers, with techniques such as SP-ICP-MS being less effective in this size domain. In this study, household laundering conditions were simulated (20-40 °C) to investigate PET microfiber release from infant outerwear. A combined ICP-AES and FTIR workflow was developed for quantitative and qualitative analysis. Washing was simulated using a color fastness tester, and samples were pretreated via Fenton oxidation and NaBr density separation. Carbon measured by ICP-AES was converted to PET mass, while FTIR confirmed polymer identity. The results showed that PET microfiber release increased from 1.75 to 2.53 mg with rising temperature, averaging 2.18 mg. FTIR peaks at 1713, 1251, and 1090 cm
