What percentage of vasculitides are non-infectious (immune mediated)?

Explanation:
Noninfectious (immune-mediated) processes account for the vast majority of vasculitis. The vessel inflammation in these conditions is driven by immune mechanisms, whereas infectious causes are relatively rare. In standard summaries, about 90–95% of vasculitides are immune-mediated, with infectious forms making up only a small minority. So the best choice is 95%.
