<p>Kaplan Meier estimate for time to clearance for all type-specific incident infections a study participant (n = 209) had before their last visit with a valid sample. The 'last observation carried forward' approach was taken when counting time to clearance (e.g. for 0 1 NA 0 pattern of HPV positivity, the NA was treated as '1' and the time was counted towards the time to clearance). This only affected skin swab samples since most people were β globin or HPV positive for eyebrows and thus their samples were not removed.</p>
