MSM: men who have sex with men; HIV: human immunodeficiency virus; HPV: human papillomavirus; GBTM: group-based trajectory modeling; expected outcomes: as suggested by GBTM; observed outcomes: as suggested by HPV infection classification. Decreased group: trajectory 1; flat group: trajectory 2; increased group: trajectory 3 in the GBTM. | |||||||||||||||||||||||||||||||||||||||||||||||||
