Multivariate Cox Regression Analysis of Variables Respectively Associated with Loss of Ambulation and LVEF < 30%

Clinical Endpoint	Cox Regression Factor	Number at Risk (%)	HR (95% CI)	p
Loss of ambulation	Corticosteroids	26 (30)	0.69 (0.35–1.34)	0.270
	Ataluren	6 (7)	0.66 (0.18–2.36)	0.520
	Residual dystrophin	47 (53)	0.05 (0.02–0.12)	<0.001
LVEF < 30%	Corticosteroids	19 (26)	0.92 (0.11–7.53)	0.938
	ACE inhibitors	56 (77)	0.57 (0.10–3.37)	0.535
	Residual dystrophin	34 (47)	0.29 (0.06–1.43)	0.127

ACE = angiotensin‐converting enzyme; CI = confidence interval; HR = hazard ratio; LVEF = left ventricular ejection fraction.
