Health utility estimates from EQ-5D-5L data collected during the ORBITA trial; higher scores indicate better health

		Utility weight
Health state	Number	Mean	SE	SD
CAD (baseline)	195	0.77	0.015	0.213
Placebo	91	0.81	0.021	0.221
PCI	104	0.83	0.023	0.212

Number =the number of patients in the sample, with a complete EQ-5D utility weight, used to estimate the mean, SE and SD.
