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

Organophosphorus flame retardants (OPFRs) are widespread environmental contaminants with bioaccumulative potential and associated human health risks. The lack of commercial reference standards for many OPFRs limits the accuracy of their quantification. In this study, a compound-independent calibration (CIC) method using gas chromatography-inductively coupled plasma mass spectrometry (GC-ICP-MS) was developed for the simultaneous quantification of seven alkyl OPFRs, with tripropyl phosphate (TnPP) as a single universal calibrant. Key parameters were optimized: a DB-5MS column (15 m × 0.25 mm × 0.10 μm) with pulsed splitless injection (70 psi, 280 °C), and ICP-MS settings including an RF power of 1600 W, sampling depth of 7.5 mm, dilution gas flow rate of 0.5 mL/min, and octopole voltage of - 5 V. The method exhibited excellent linearity (R
