Effect of Diagnosis (Chronic Migraine vs. NDPH) on odds of benefit in logistic regression models

Predictor(s) in the model	OR	95% CI	p-value
Diagnosis of chronic migraine (CM) alone	3.3	0.7–15.8	0.14
CM+ medication overuse	3.5	0.7–17.9	0.13
CM+medication overuse+age*	3.7	0.7–19.5	0.12
CM+medication overuse+age+sex	3.1	0.6–17.2	0.20
CM+medication overuse+age+sex+sensory change (Fully adjusted model)	3.4	0.6–19.6	0.17

CM=chronic migraine;

^*age was a continuous variable in all of these models CI=confidence interval
