Comparison of PR3 levels in different clinical subgroups

	Fisher's PLSD, P-value
Vasc-pat versus HBD	<0·0001 (s.)
Vasc-pat versus DC	<0·0001 (s.)
Vasc-pat, remission versus smouldering	0·21 (n.s.)
Vasc-pat, severe outcome versus non-severe outcome	0·44 (n.s.)
Vasc-pat, relapse versus no relapse	0·74 (n.s.)

Vasc-pat = all vasculitis patients. HBD = healthy blood donors. DC = disease controls. Severe outcome = severe organ damage, start in dialysis or death due to vasculitic complications during 6 years’ follow-up. Relapse = at least one relapse during 6 years’ follow up. n.s. = non-significant, s. = significant.
