Calibrated HIV incidence for select populations from 1998–2002 as a function of socioeconomic and demographic metrics of 80 U.S. cities in 2000 (unless otherwise indicated).

HIV association factor is the ratio between HIV incidences for Q4 and Q1, or, for starred metrics (*), Q1:Q4* (for easier comparison where a smaller metric value theoretically predicts greater risk). For each population, HIV incidence was obtained by dividing the total number of HIV cases for that exposure category by the total estimated number of individuals in that category (i.e. number of black, white or LGB individuals). Boldfaced = p<0.05 for similarity between Q1 and Q4 (Student's T-test).

HIV关联因子（HIV association factor）指第四季度（Q4）与第一季度（Q1）的HIV感染率之比；对于带星号（*）的指标，其比值为Q1:Q4*，此举便于开展对比分析，理论上该指标数值越小，预示的感染风险越高。针对每一类人群，HIV感染率的计算方式为：该暴露类别下的HIV确诊总例数除以该类别的估计总人数（即黑人、白人或女同性恋、男同性恋、双性恋（LGB）个体）。文本中以粗体标注的结果，代表通过Student氏t检验（Student's T-test）对Q1与Q4的相似性进行检验时，所得p值小于0.05。
