From: Shift from chronic to episodic migraine frequency in a long-term phase 3 study of galcanezumab

Percentage of patients shifting from CM to EM frequency during the 3-month double-blind treatment period. The percentage of patients shifting to EM frequency is shown at Month 3 (A) and at all 3 Months (B). EM is defined as < 8 migraine headache days/month or < 15 headache days/month, LFEM as < 8 migraine headache days/month, and VLFEM as < 4 migraine headache days/month. Thus, EM includes LFEM and VLFEM, and LFEM includes VLFEM. *p < 0.05, **p < 0.01, ***p < 0.001 (vs. placebo). Abbreviations: EM, episodic migraine, LFEM, low frequency episodic migraine; VLFEM, very low frequency episodic migraine
