Personal care products exposure patterns and prostate cancer: evidence from a case-control study in Mexico City.
Article in Journal of exposure science & environmental epidemiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPersonal care products (PCPs) use has been associated with a high risk of hormone-sensitive cancers in women. However, this association is poorly understood in hormone-sensitive cancers in men.
objectiveTo investigate the association between PCPs use and prostate cancer (PC) and PC histological differentiation in men from Mexico City.
methodsWe analyzed the information from 400 histologically confirmed incident PC cases and 801 population controls matched by age (±5 y). The usage frequency (daily, weekly, or less, and non-use) of deodorant, body lotion, shampoo, perfume, and shaving or after-shaving products was evaluated based on a structured questionnaire. Using the K-means approach, we selected three patterns according to the usage frequency and number of PCPs used: high, intermediate, and low. Multivariable non-conditional logistic regression models adjusted by selected confounders were conducted to estimate the association between the use of PCPs (patterns, individual products, and number of products used daily) and PC, as well as PC histological differentiation.
resultsCompared to the low exposure pattern, the high (OR: 2.6 95% CI: 1.8-3.8) and intermediate (OR: 1.3 95% CI: 1.0-1.8) PCPs patterns were associated with higher odds of PC. Similarly, the intermediate exposure pattern was significantly associated with poorly differentiated PC (OR: 1.8 95% CI: 1.1-2.9). The daily use of perfume was the most consistent PCP associated with PC (OR IMPACT STATEMENT: This study provided evidence that high exposure to personal care products (PCPs) is associated with prostate cancer. Our findings are consistent with those observed regarding hormone-sensitive female cancer and suggest the potential contribution of PCPs to prostatic carcinogenesis.
