Group A (n = 38), B (n = 186) and C (n = 29) were homogeneous by baseline HIV-RNA (p = 0.29), and GSS (p = 0.22), while baseline CD4 levels showed a significant trend towards higher CD4 counts in simpler regimens (means: A = 351; B = 281 and C = 164/mmc, p = 0.0009, Kruskall–Wallis test), reflecting a tendency in prescription.
