Risk factors associated with HIV infection in bivariable and multivariable analysis.

OR: odds ratio. 95% CI: 95% Confidence interval. STI: sexual transmitted infection.1Genital symptoms: vaginal discharge (400), painful urination (133), lower abdominal pain (300), vaginal itching or burning (261), pain during intercourse (213), vaginal sore (54).2Missing data: number HIV test in lifetime = 1.3Not applicable (no PP) = 97. When comparing ‘Do not know’ to ‘Yes’ the aOR = 1.72 (1.12–2.45).*Crude OR and P-value for the association between each variable and HIV-1 infection (chi-square test).§P-value from chi-square test for trend.ξOR and P-value adjusted for all variables in the table (likelihood ratio test).OR：比值比（odds ratio）；95% CI：95%置信区间（95% Confidence interval）；STI：性传播感染（sexual transmitted infection）。1. 生殖道症状：阴道分泌物增多（400）、排尿疼痛（133）、下腹痛（300）、阴道瘙痒或灼热感（261）、性交痛（213）、阴道溃疡（54）。2. 缺失数据：终身HIV检测次数的缺失值为1。3. 无对应项（无PP）的案例数为97。当以“不知道”组与“是”组进行比较时，调整后比值比（adjusted odds ratio，简称aOR）为1.72（1.12~2.45）。* 各变量与HIV-1感染关联的粗比值比及P值（卡方检验）。§ 趋势检验的卡方检验P值。ξ 针对表格中所有变量进行校正后的比值比及P值（似然比检验）。
