	Controls	ICP	Alcoholic CP	Sjögren’s syndrome
Age	56.5 (12.8–80)	56 (12.8–82)	52 (35–66.7)	62 (36.1–77.3)
Sex (F/M)	23/31	23/31	5/81** ††	32/1**††
Duration of disease (y)	0	4 (0.6–22.3)	8 (0.7–19.7)	7 (1–20)
Diabetes mellitus	0% (0/54)	40.7% (22/54)**	66.3% (57/86)**††	3% (1/33)††
Steatorrhoea	0% (0/54)	35.2% (19/54)**	53.5% (46/86)**†	0% (0/33)††

Results are expressed as median (5th and 95th percentiles), or as percentage.

CP, chronic pancreatitis; ICP, idiopathic chronic pancreatitis.

Duration of disease is the time from onset of the disease. Diabetes mellitus diagnosis was established following the WHO criteria. Steatorrhoea was diagnosed when faecal fat excretion was >7 g/24 hour in faeces of 72 hours.

Statistical significance was as follows: **p<0.01 versus controls; †p<0.05, ††p<0.01 versus ICP.
