Quantitative Analysis and Risk Assessment of Polycyclic Aromatic Hydrocarbons Using Gas Chromatography-Mass Spectrometry from Herbs and Spices Distributed in South Korea.

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.
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
In this study, four polycyclic aromatic hydrocarbons (4PAHs: benz[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene (BaP)) were quantified in 110 herb and spice products marketed in South Korea. A validated gas chromatography-mass spectrometry (GC-MS) method achieved high sensitivity with limits of detection (LOD) ranging from 0.08 to 0.18 µg/kg and limits of quantification (LOQ) ranging from 0.24 to 0.55 µg/kg, with recoveries consistent with the Association of Official Analytical Chemists guidelines. Among the tested items, oregano contained the highest BaP concentrations with 7.13 µg/kg, while overall concentrations of the sum of 4PAHs remained below European Union limits. The BaP-based toxic equivalent (TEQ
