Prevalence of inhibitory and stimulatory anti-human muscarinic acetycholine receptor type 3 (mAchR3) antibodies in patients with different disorders known to be associated with functional autoantibodies

		Stimulatory antibodies (≥ 130%)	Inhibitory antibodies (≤ 70%)
Diseases	No. patients tested	Number (%) positive
