Hazard ratios of OA discontinuation

	HR	95%CI	P
Severity (Moderate)	1.32	0.50–3.53	0.5731
age†	0.96	0.91–1.01	0.1933
sex	3.38	1.26–9.15	0.0154
Psychiatric Disorder (+)	2.01	0.73–5.54	0.18
age†	0.96	0.90–1.01	0.185
sex	3.07	1.14–8.27	0.0265

HRs were calculated using multivariate Cox proportional hazard model, and P-values were calculated using Wald test. HR for age(†) is shown as a unit risk ratio.
