Association between PM2.5 and skin redness features in Taiwan.
Article in PLOS global public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Air pollution, particularly fine particulate matter (PM2.5), has been associated with various health issues, but its effects on skin health, specifically skin redness, remain underexplored. This study aims to examine the relationship between PM2.5 exposure and skin redness, with a focus on the role of sebum production in different age groups. A total of 472 participants from two communities in Taiwan in two age groups (20-59 years, n=240; over 60 years, n=232) were included in the study. PM2.5 exposure levels were estimated using land use regression models based on participants' residential addresses. Skin redness area was assessed using the VISIA Imaging System. Linear regression analyses were conducted to examine the association between PM2.5 and redness area, adjusting for demographic, lifestyle, and ultraviolet exposure. Results showed a significant positive association between PM2.5 levels and redness area in both age groups. In the 20-59 age group, each unit increase in PM2.5 corresponded to a 1.70-unit increase in redness area (95% CI: 0.32 - 3.07, p < 0.01), while in the over-60 group, the increase was 2.63 units (95% CI: 1.19 - 4.08, p < 0.001). Additionally, porphyrins showed a positive association with redness area among the 20-59 age group (p < 0.05), while no significant association was found in the over-60 group. This study suggests a linkage between PM2.5 exposure and skin redness area, indicating that air pollution may be a contributing factor to skin health issues. The findings suggest that the interaction between lipophilic and carcinogenic substances in PM2.5 and porphyrins could elevate redness area levels and potentially increase the risk of chronic skin conditions and skin cancer.
