Cumulative incidence of relapse in patients with P. vivax infection treated with three different PQ regimens in the Peruvian Amazon Basin

	5 days	7 days	14 days
N	169	156	162
All relapses	48 (28.4%)	16 (10.3%)	22 (13.6%)
95% CI	21.7–35.8	6.0–16.1	8.7–19.8
Genotyping-adjusted relapses	26 (15.4%)	8 (5.1%)	12 (7.4%)
95% CI	10.3–21.7	2.2–9.9	3.9–12.6

All relapses: 5 versus 7 days, P < 0.001; 5 versus 14 days, P = 0.001; 7 versus 14 days, P = 0.361. Genotyping-adjusted relapses: 5 versus 7 days, P = 0.003; 5 versus 14 days, P = 0.023; 7 versus 14 days, P = 0.403.
