Disinfection Byproducts, Oxidative Stress, and Sleep Quality among Healthy Chinese Men.

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
Toxicological studies show that disinfection byproducts (DBPs) adversely affect neurological and psychiatric symptoms, which have been linked to poor sleep quality. This cohort study explored the associations between DBP exposure, oxidative stress, and sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI) questionnaire among young healthy Chinese men who provided 710 blood and 2647 repeated urinary samples over 3 months. We measured trihalomethanes in blood and haloacetic acids and oxidative stress markers in urine samples. In adjusted models, each 2.7-fold increase in urinary trichloroacetic acid (TCAA) concentrations was associated with a greater PSQI score of 0.29 (95% confidence interval: 0.07, 0.50). A clear dose-response relationship was observed when TCAA concentrations were included as quartile variables (
