QuEChERS analytical approach for monitoring endocrine-disrupting chemicals in human urine.

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
This study introduces an analytical method for the determination of endocrine-disrupting chemicals (EDCs) in human urine samples, employing QuEChERS as a clean-up step for the first time in this biological matrix. Sample preparation was rigorously optimized through the evaluation of sample and final dilution volumes, balancing the need to reduce matrix interference without sacrificing sensitivity. High-performance liquid chromatography coupled with a triple quadrupole-time-of-flight mass spectrometer (HPLC-QTOF) was employed, enabling the detection of 13 target analytes (five OPEs, five phthalates, and three parabens' metabolites). Chromatographic separation was achieved in 16 min, and mass spectrometry parameters were fine-tuned to maximize signal sensitivity. The method was validated by assessing parameters such as selectivity, linearity, precision, accuracy, and sensitivity. Linearity of response was demonstrated for all of the compounds (r
