* Row percentage across insurance physicians and across offices respectively, by categories (yes) of outcome measures. Number of clients: n = 83755 clients for NCSE and MDWC; n = 64190 clients for FIS. NSCE = no sustainable (long-term) functional capacities anymore, or restrictions in working hours up to 30 hours (category = yes); FIS0 = functional incapacity score (score 0 = yes); FIS123 = functional incapacity score (score 1 up to 3 = yes); FIS456 = functional incapacity score (score 4 up to 6 = yes); MWDC = maximum work disability class 80%-100% (category = yes).
