Characteristics of the Leuven ND cohort and factors associated with TDR.

*Fisher's test or logistic regression techniques were used. †High prevalent countries were defined as HIV-prevalence over 1% in adult population (UNAIDS 2012), § CDC stage was defined according to 2008 definitions [47], ∥CD4 count at diagnosis (median 345, IQR: 158–496) was not statistically different from CD4 count at time of sampling. ¶Viral load at diagnosis (median 4.76 IQR: 4.04–5.31) was not statistically different from viral load at time of sampling. Abbreviations: %: percentage, CDC: Center for Disease Control and Prevention, CI: Confidence interval, IVDU: Intravenous drug user, IQR: interquartile range, MSM: men who have sex with men, n: number, OR: odds ratio, SD: standard deviation.

* 本研究采用Fisher精确检验或逻辑回归分析方法。
† 高流行国家定义为成人HIV感染率超过1%（联合国艾滋病规划署[UNAIDS]，2012）；
§ 美国疾病控制与预防中心（Center for Disease Control and Prevention）分期依据2008年标准[47]；
∥ 诊断时的CD4细胞计数（中位数345，四分位距（interquartile range，IQR）：158~496）与采样时的CD4细胞计数无统计学差异；
¶ 诊断时的病毒载量（中位数4.76，四分位距4.04~5.31）与采样时的病毒载量无统计学差异。
