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
A method of quantifying glyphosate (Gly) in human urine by means of MonoSpin TiO extraction and 9-fluorenylmethoxycarbonyl chloride (FMOC-Cl) derivatization with isotope dilution mass spectrometry (IDMS) was investigated and optimized. The method's quantification limit under optimized conditions was 0.3 µg/kg for FMOC-Gly, which was comparable to or lower than those described in previous studies. When a spike test using human urine samples was carried out with optimized analytical conditions, the trueness for FMOC-Gly was as follows: 101.6-104.9% for a spike level of 0.5 µg/kg and 99.2-101.0% for a spike level of 30 µg/kg. The intra-day repeatability and inter-day reproducibility were <6.5%. The spike test results for validation between the "with" and "without" derivatization methods were comparable at 1 µg/kg. Our results indicate that using MonoSpin TiO extraction and FMOC-Cl derivatization with IDMS is an accurate method for analyzing Gly in human urine.
