Study 3
Antigen avoidance
• Baseline	5 (4)^a	58	7		2–26		73^a	15^a		11–32^a
• Follow up	5 (4)^a	126	26		4–42		51^a	13^a		6–19^a
Corticosteroids
• Baseline	6	46	8		4–12		74	12		4–23
• Follow up	6	123	18		13–36		97	14		6–32

^aIn study 3, one horse of the antigen avoidance group was not considered for the statistical analysis of the pulmonary arteries smooth muscle mass quantification because at the baseline only one immunostained artery was measurable.
