Factors associated with adherence to post-exposure prophylaxis among dental professionals in Brazil.
Article in Brazilian oral research, 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
This study analyzed the influence of sociodemographic, occupational, and accident-related factors on adherence to post-exposure prophylaxis (PEP) among dental professionals. A cross-sectional study was conducted using secondary data from the Brazilian Notifiable Diseases Information System, covering incidents of biological material exposure from 2018 to 2023 across all federal units. PEP adherence was the outcome analyzed, and related factors included sociodemographic, occupational, and accident characteristics. Descriptive, bivariate, and multivariate logistic regression analyses were performed (α = 5%). A total of 15,650 notifications involving dental professionals were analyzed, representing 3.91% of all cases of occupational exposure, with a PEP adherence rate of 91.0%. The exposed professionals had a mean age of 32.5 years (SD = 10.4), were predominantly women (76.6%), of White race/ethnicity (65.4%), and had higher education (79.7%). The mean work experience was 3.6 years (SD = 6.8). In the adjusted model, adherence was associated with lower educational attainment (OR = 0.71; 95%CI: 0.58-0.88), younger age (OR = 0.99; 95%CI: 0.98-0.99), and longer work experience (OR = 1.02; 95%CI: 1.01-1.03). Percutaneous exposure (OR = 1.39; 95%CI: 1.16-1.67), contact with blood (OR = 1.47; 95%CI: 1.18-1.82), and dental procedure-related accidents (OR = 1.35; 95%CI: 1.07-1.70) increased the likelihood of adherence. Hepatitis B vaccination (OR = 1.96; 95%CI: 1.62-2.36) was associated with increased adherence to PEP. Adherence to PEP was influenced by multiple factors, highlighting the need for effective strategies to improve adherence and occupational safety among these professionals.
