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

The migration of harmful plastic additives with diverse polarities and boiling points from plastic food contact materials (FCMs) poses a risk to human health, necessitating simple and effective analytical methods. Herein, a π-conjugated truxene (Tr) was covalently bonded with cucurbit[6]uril (Q[6]) to afford a novel Q[6]-Tr compound, which was fabricated as both a solid-phase microextraction (SPME) fiber coating and a gas chromatography (GC) stationary phase to establish an integrated SPME-GC system. The proposed method determined 9 plastic additives from 4 categories, showing good linearity (R
