EQ-5D utility index score | 0.040 (0.021) | 0.027 (0.038) | 0.013 (−0.065, 0.091) |
EQ-5D VAS score | 2.2 (1.8) | 1.8 (3.4) | 0.4 (−6.6, 7.4) |
aHigher scores represent better outcomes on the EORTC QLQ-C30 functioning domains and worse outcomes on the EORTC QLQ-C30 symptom/single-item scales. Higher scores represent better outcomes on the EQ-5D utility index and EQ-5D VAS.
bA positive difference favors nivolumab on the EORTC QLQ-C30 functional domains and EQ-5D; negative difference favors nivolumab on the EORTC QLQ-C30 symptom scales. Differences in mean changes were not significant for all domains/scales.
cSignificant deterioration within arm (P < 0.05).
dSignificant improvement within arm (P < 0.05).
