Association between sociodemographics and abnormal anal cytology among study participants.

Abbreviation: ASCUS = atypical squamous cells of undetermined significance; ASC-H = atypical squamous cells but cannot exclude HSIL; ASIL = anal squamous intraepithelial lesions; HAART = highly active antiretroviral therapy; HIV = human immunodeficiency virus.*Sum may not always add up to total because of missing data.#Participants with normal cytology was treated as control.§CD4 cell count was measured in the past three months.缩写说明：ASCUS：意义未明确的非典型鳞状细胞（atypical squamous cells of undetermined significance, ASCUS）；ASC-H：非典型鳞状细胞，不排除高度鳞状上皮内病变（atypical squamous cells but cannot exclude HSIL, ASC-H）；ASIL：肛门鳞状上皮内病变（anal squamous intraepithelial lesions, ASIL）；HAART：高效抗反转录病毒治疗（highly active antiretroviral therapy, HAART）；HIV：人类免疫缺陷病毒（human immunodeficiency virus, HIV）。*由于存在数据缺失，各项求和值未必与总计数完全一致。#细胞学检查结果正常的受试者被设为对照。§CD4细胞计数为近三个月内的检测结果。
