Characteristics of patients stratified by HIV RNA levels below the limit of quantification and low-level viraemia defined as quantifiable HIV RNA levels <200 copies/mL and virological failure defined as HIV RNA levels ≥200 copies/mL.

Abbreviations: LLV, low-level viraemia; VF, virological failure; VL, viral load; NRTIs, nucleoside reverse transcriptase inhibitors; NNRTI, non-nucleoside reverse transcriptase inhibitor; PI/r, boosted protease inhibitor; INSTI, integrase inhibitor; BLQ, below the limit of quantification; cART, combination antiretroviral therapy;
1 Comparison between quantifiable HIV RNA levels <200 copies/mL (LLV) and HIV RNA levels below the limit of quantification (BLQ).
2 Comparison between HIV RNA levels ≥200 copies/mL (VF) and HIV RNA levels below the limit of quantification (BLQ).
3 Interruptions prior to 6 months stable cART of the respective cART regimen.
4 Diabetes mellitus prior to 6 months stable cART of the respective cART regimen.
5 cART duration until 6 months stable cART of the respective cART regimen.
6 Whether the respective cART regimen is a first-line cART or not.

缩写说明：LLV（low-level viraemia，低度病毒血症）；VF（virological failure，病毒学失败）；VL（viral load，病毒载量）；NRTIs（nucleoside reverse transcriptase inhibitors，核苷类逆转录酶抑制剂）；NNRTI（non-nucleoside reverse transcriptase inhibitor，非核苷类逆转录酶抑制剂）；PI/r（boosted protease inhibitor，强化蛋白酶抑制剂）；INSTI（integrase inhibitor，整合酶抑制剂）；BLQ（below the limit of quantification，低于定量限）；cART（combination antiretroviral therapy，联合抗逆转录病毒治疗）；
1. 可定量HIV RNA水平<200拷贝/mL（低度病毒血症LLV）与低于定量限（BLQ）的HIV RNA水平之间的对比分析；
2. HIV RNA水平≥200拷贝/mL（病毒学失败VF）与低于定量限（BLQ）的HIV RNA水平之间的对比分析；
3. 对应联合抗逆转录病毒治疗（cART）方案在达到6个月稳定cART治疗前的治疗中断情况；
4. 对应cART方案在达到6个月稳定cART治疗前的糖尿病病史；
5. 采用对应cART方案直至达到6个月稳定cART治疗的疗程时长；
6. 对应cART方案是否为一线联合抗逆转录病毒治疗方案；

基于低于定量限的HIV RNA水平、定义为可定量HIV RNA<200拷贝/mL的低度病毒血症，以及定义为HIV RNA≥200拷贝/mL的病毒学失败进行分层的患者特征。
