Key model parameters and costs.

*All ranges are uniformly distributed**Two AIDS stages were included because during the final months before death, patients have limited sexual activity*** Due to window phase of p24 antigen testing† Includes cost of false positives that require additional testing (0·7% false positivity rate)‡ Four times the length of a normal outpatient clinic appointment§ The average cost per person per stage of infection/treatment. Includes diagnosis, treatment, personnel costs. Averaged per patient per year.Key model parameters and costs.*所有区间均服从均匀分布**纳入两个艾滋病（AIDS）感染阶段，原因在于患者临终前数月内性活动受限**由于p24抗原检测（p24 antigen testing）的窗口期†，包含需进行额外检测的假阳性结果对应的成本（假阳性率为0.7%）‡ 时长为常规门诊预约时长的四倍§ 各感染/治疗阶段的人均年均成本，涵盖诊断、治疗及人力成本，按患者年平均值统计。关键模型参数与成本。
