- Note: SE Standard error, Intercept, the EQ-5D-3L level in January 2006; Time, number of months from January 2006; VBRP, indicates the introduction of the STHLM-VBRP in the end of 2013; which is 92 months after January 2006 (Time = 92); Time after, number of months after the introduction of VBRP (hence Time-91); July, indicates the month of July
- Parameter estimates from the segmented regression analysis predicting the mean monthly EQ-5D-3L level among surgically treated patients before and after the introduction of the STHLM-VBRP, 2006–2015. The introduction of the reimbursement program had no effect on level (VBRP) nor trend (Time after) of EQ-5D-3L
