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

backgroundTriclosan, a widely-used antimicrobial in personal care products, has shown endocrine disrupting activity in experimental studies. However, there is limited evidence from epidemiologic studies on health effects.

objectiveTo examine the association between urinary triclosan concentrations and semen quality.

methodsA total of 262 men enrolled in the Environmental and Reproductive Health (EARTH) Study provided 581 paired urine and semen samples (2009-2017). Urinary triclosan concentrations were quantified and semen analysis was evaluated according to WHO guidelines. We used linear mixed regression models to estimate the associations between specific gravity-adjusted urinary triclosan concentrations with semen parameters, with a random intercept to account for multiple samples per man and adjusting for age, body mass index (BMI), smoking, physical activity, sexual abstinence time, and season and year of samples' collection.

resultsMen had a mean (standard deviation) age of 36.6 (5.24) years and BMI of 27.9 (5.94) kg/m

conclusionDespite the lack of observed dose response relationship, we found consistent patterns of lower percent morphologically normal sperm for men with urinary triclosan in the 2nd or 3rd quartile compared to undetectable concentrations.This association was stronger for samples obtained prior to 2013 when triclosan was more often detectable in urine.
