^*Out of the non-complete cases, 100 out of 124 patients had complete information for calculation of EQ-5D-5L utilities in the CGAHAH group and 56 out of 71 patients in the Hospital group.

^**As the main economic evaluation only estimated complete cases, the number of patients for complete cases was 559 out of 563 patients in the CGAHAH group and 272 out of 274 patients in the Hospital group who had complete information for the calculation of EQ-5D-5L utility. Out of the incomplete cases, 115 out of 124 had complete information in the CGAHAH group and 59 out of 71 patients in the Hospital group for calculation of EQ-5D-5L utilities.

^***This is the number for patients who had seen their primary care physician at the surgery, at home or by telephone.
