Whereas we did not observe a significant difference in PFS [CHT: 3.0 months (95% CI 1.4-4.6 months) versus nCHT: 3.2 months (95% CI 2.8-3.6 months), P = 0.725], there was a strong trend towards longer OS in the CHT group [CHT: 15.5 months (95% CI 8.0-23.0 months) versus nCHT: 5.3 months (95% CI 0-12.5 months), P = 0.052] ( Figure 1 C).
