The Perfil-es study demonstrated that, while non-nucleoside reverse transcriptase inhibitor (NNRTI)-based initial antiretroviral therapy (ART) is more frequently used in human immunodeficiency virus (HIV)-infected naïve patients, ritonavir-boosted protease inhibitors (PI/r)-based regimens are the preferred option in patients with advanced infectious stages or high baseline viral load. The present analysis focused on the second phase of the Perfil-es study, where sociodemographic and clinical data were retrospectively collected from patients starting NNRTI- or PI/r-based regimens in order to identify factors that could influence the choice of initial ART. Patients' characteristics were compared by both bivariate and multivariate analyses.

Methods: An observational retrospective study performed in 65 Spanish hospitals.
Results: Was a total of 1,687 starts: 53% with NNRTI-based regimen and 42% with PI/r, and of the 642 patients analyzed, 72% had a CD4 count<350 cells/μl.
