Multi-level univariable logistic regression models for virological response in patients with GRT+rPRT compared to GRT *

	n	OR (95% CI)	p-value
All patients	1158	0.85 (0.59 - 1.24)	0.41
Patients with any failure	770	1.16 (0.73 - 1.82)	0.53
Patients with >2 previous failures	533	1.45 (1.00 - 2.09)	0.05

* Models are hierarchical with follow-up centre included as a random effect. Virological response is defined as a reduction by ≥1.5 log HIV-1 RNA viral load or less than 50 copies/mL
