From: Repeat HIV-testing is associated with an increase in behavioral risk among men who have sex with men: a cohort study

   2–3 HIV tests (n = 1384; 47 HIV+) median time first/last test 503 days (IQR, 317–845 days) 4–5 HIV tests (n = 565; 22 HIV+) median time first/last test 844 days (IQR, 567–1229 days) 6 or more tests (n = 508; 18 HIV+) median time first/last test 1333 days (IQR, 920–1705 days)
