I am having difficulties understanding the following table from the study Incidence and clearance of genital human papillomavirus infection in men (HIM): a cohort study.
I think I might be reading the below table completely wrong, but am I right with the following - let's take the row for HPV type 51 for example:
- 72 men tested positive at the first test of the study for HPV type 51? (prevalence)
- 108 other men (not including the 72 men who tested positive at the start of the study) tested positive for HPV type 51 at some point in time during the 4 years of the study. (incident infections)
- Those in sum 180 HPV type 51 positive men tested in sum 91 more times positive for HPV type 51 (new infections)
- Of those 180 HPV type 51 positive men 62 infections were cleared. (Cleared infections)
If not, could anybody explain how to make sense of this table?
