  1. Note: SE Standard Error, Intercept, The ODI level in January 2006; Time, number of months from January 2006; VBRP, indicates the introduction of the STHLM-VBRP at the end of 2013; which is 92 months after January 2006 (Time = 92); Time after, number of months after the introduction of VBRP (Time-91); July, indication of the month of July
  2. Parameter estimates from the segmented regression analysis predicting the mean monthly Oswestry disability index (ODI) 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 ODI
