	Poor/moderate work ability compared to lifetime best^b	73.7	25.1
	Good/excellent work ability compared to lifetime best^b	26.3	74.9
Work ability regarding physical demands	Md, Mean (±SD)^c	5.0, 4.4 (0.7)	5.0, 4.5 (0.6)
	Lower work ability regarding physical demands^d	46.0	41.3

	Higher work ability regarding mental demands^d	34.4	40.8

Figures are percentage if not stated otherwise
^aWork ability compared with lifetime best was ranging from 0 (= worse) to 10 (= best)
^bWork ability compared with lifetime best was dichotomized into: Poor/moderate work ability compared to lifetime best (=0) and good/excellent work ability compared to lifetime best (=1)
^cWork ability regarding physical and mental demands was ranging from 0 (= worse) and 5 (= best)
^dWork ability regarding physical and mental demands was dichotomized into: lower work ability (=0) and higher work ability (=1)
