Analysis identifies HIV-1 risk factors in men, suggesting effective Pre-Exposure Prophylaxis (PrEP) strategies.

The tool estimates that 229,000 HIV-1 cases could be averted with proper PrEP adherence among men.
The area under the ROC curve was 0.80, indicating good predictive accuracy for HIV-1 risk assessment.
