1
Twelve-month incidence is the rate of male acquiring an infection during any given twelve month period (i.e., year) in the HIM study
2
P-value from log-rank test for HPV incidence by smoking status
3
Smoking status was analyzed by two different approaches: 1) among baseline only status and 2) among men who reported the same smoking status at both the baseline and their last follow-up (LFU)
