Abbreviations: ART: Antiretroviral therapy; RPV: Rilpivirine; EFV: Efavirenz; 3TC: Lamivudine; ABC: Abacavir; TDF: Tenofovir disoproxil fumarate; FTC: Emtricitabine; AZT: Zidovudine; NVP: Nevirapine; DRV: Darunavir; RTV: Ritonavir; ATV: Atazanavir; PI: Protease inhibitor; TAF: Tenofovir alafenamide; DTG: Dolutegravir; CAB: Cabotegravir.
§The pooled analysis of the ECHO and THRIVE trials included 686 patients in the RPV arm (RPV 25 mg/day plus one of the following regimens: TDF/FTC, AZT/3TC or ABC/3TC) and 682 patients in the EFV arm (EFV 600 mg/day plus one of the following regimens: TDF/FTC, AZT/3TC or ABC/3TC).
*Double-blinded to RPV doses; open-label to placebo. We considered the arm with an RPV dose of 25 mg/day in the meta-analysis.
**Double-blinded to cabotegravir doses; open-label to the assignment of cabotegravir (and RPV in the maintenance phase) or EFV.
^60, 60, and 61 patients treated with 10 mg, 30 mg and 60 mg of cabotegravir, respectively.
