Table 4. Incidence and adjusted hazard ratio of respiratory failure associated with mycobacterium avium complex in patients with non-TB mycobacterial infection.

Variables		Event	PY	Rate#	IRR*(95% CI)	Adjusted HR†(95% CI)
Non-TBmycobacterial infection	Comparison cohort	675	66162	10.2	1.00	1.00
	MAC	307	3947	77.8	7.62(6.95–8.36)	3.51(2.98–4.12)

PY, person-years; Rate^#, incidence rate, per 1,000 person-years; IRR^*, incidence rate ratio; CI, confidence interval; Adjusted HR^†: multiple analysis including age, sex, income and comorbidities; NTM, non-TB mycobacterial infection; MAC, mycobacterium avium complex; Non-MAC, none mycobacterium avium complex; p<0.001.
