I found it odd that Auvert and colleagues did not discuss the finding that Catholics and Protestants made up only 11.1% of the study population (Table 2, line 5) yet accounted for 36.2% of the new HIV infections (Table 4, line 7) until I realized that there is an error in either Table 2 or Table 4.

According to Table 2, there were 360 Catholics and Protestants in the study, and they had an average follow-up period of 5.27 years (1845 py/360 persons. According to Table 4, there were 1225 persons in the religious category 'Other' and they had an average follow-up period of 0.47 years (576 py/1225 persons).

These numbers are not reasonable given the other information about the study. It seems most likely that the percentages for the categories of 'Catholics and Protestants' and 'Other' are accidentally reversed in Table 2.
