We found that higher EQ5D-VAS scores were associated with CRS patients who classified their symptom control as “Very” (adjusted β=15.74, 95% CI: 5.44 to 26.04, P=.003) and “Completely” (adjusted β=14.24, 95% CI: 2.98 to 25.52, P=.014) compared to patients who classified their symptom control as “Not at all.” This was also true for higher EQ5D-HUV which was associated with patient-reported CRS symptom control of “A little” (adjusted β=0.10, 95% CI: 0.01 to 0.18, P=.024), “Somewhat” (adjusted β=0.08, 95% CI: 0.00 to 0.17, P=.049), “Very” (adjusted β=0.13, 95% CI: 0.05 to 0.21, P=.002) and “Completely” (adjusted β=0.18, 95% CI: 0.09 to 0.27, P<.001).
