Skin phototypes, UV exposure, and socioeconomic vulnerability in a region of the Brazilian Amazon.

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 aimed to describe the skin phototypes of the sampled population in a region of the Brazilian Amazon using the Fitzpatrick scale, as well as to investigate sun exposure habits and associate photoprotection practices with socioeconomic vulnerability conditions. Data were obtained from a household survey conducted in 2022 by Community Health Agents of three Municipal Health Departments, covering 1,442 urban adults. Descriptive statistics, Pearson’s Chi-squared test with Yates’ correction, and Odds Ratios were applied to assess associations between socioeconomic vulnerability and photoprotection practices. Results showed a predominance of melano-protected phototypes (V and VI, 49.2%), followed by melano-competent (III and IV, 43.9%) and melano-compromised (I and II, 7%). While lighter phototypes often adopt sun protection, darker phototypes face greater exposure linked to work and culture. Sunscreen adherence was low across all phototypes, with alternative methods, such as wearing hats and clothing, being more common. Socioeconomic vulnerability increased the likelihood of not adopting photoprotection practices by 2.28 times. These findings highlight that low sunscreen adherence, combined with socioeconomic vulnerability, substantially increases the risk of inadequate photoprotection in the Brazilian Amazon.
