List of the most commonly prescribed classes of and specific antiretroviral agents and their combinations used in HAART and ART non-HAART ART regimens among patients attending public HIV treatment facilities in Brazil (n = 463) between January 1, 1995 and December 31, 2001.

*A total of 36 unspecified ART regimens (HAART = 22 and ART non-HAART = 14) were cumulatively used for at least one day, 780 times during the study period∼
**See footnotes, Table 1
***Protease inhibitors (includes ritonavir-boosted regimens)
^A total of 177 specific ART regimens were cumulatively used for at least one day, 1421 times during the study period∼
∼Note that the number of ART regimens cumulatively used during the study period exceeds the total study population because, for those on ART, more than one regimen may have been prescribed during the study period

* 总计有36种未明确分类的抗反转录病毒治疗（Antiretroviral Therapy, ART）方案，其中高效抗反转录病毒治疗（Highly Active Antiretroviral Therapy, HAART）方案22种、非HAART的ART方案14种，在研究期间累计被使用至少1天，总使用频次达780次∼
** 详见表1及注释
*** 蛋白酶抑制剂（Protease Inhibitors）：包含经利托那韦（Ritonavir）增强的治疗方案
^ 总计有177种明确分类的ART方案，在研究期间累计被使用至少1天，总使用频次达1421次∼
∼ 注：研究期间累计使用的ART方案总数多于研究总人群数，原因在于接受ART治疗的患者在研究期间可能被开具过不止一种治疗方案
