Legend: CM-MO Chronic migraine with medication overuse, EM Episodic migraine. B is the coefficient in log-odds units used in predicting the dependent variable (EM versus CM-MO) from the independent variable. S.E. represents standard errors associated with B coefficients, while Wald signifies the Wald chi-square value, with df representing degrees of freedom. Exp(B) indicates odds ratios for the predictors, obtained through exponentiation of the coefficients. 95% CI or 95% confidence intervals denotes the confidence intervals for the odds ratios Exp(B)
