Patients’ ages and health-related work ability

	Studies including PC (n = 22)	Studies excluding PC (n = 227)
Productive age (18–65)
Yes (mean age 18–70)	19 (86 %)	163 (72 %)
No (mean age >70)	−	21 (9 %)
Unknown	3 (14 %)	42 (19 %)
Work ability based on severity of illness
Likely to be able to work	21 (95 %)	146 (64 %)
Doubtful	1 (5 %)	8 (4 %)
Unlikely to be able to work	−	73 (32 %)

These estimations were based on a medical doctor’s expert opinion regarding the severity of disease of the patient populations
