Correlations of changes in L_PRECUN and L_SPFG z-scores and changes in clinical data.

	L_PRECUN z-score changes	L_SPFG z-score changes
Monthly mean VAS score change, mean ± SD	r = −0.172, P = 0.557	r = 0.224, P = 0.441
Monthly headache attack changes, mean ± SD	r = −0.302, P = 0.293	r = 0.069, P = 0.814
Monthly headache day changes, mean ± SD	r = −0.002, P = 0.993	r = 0.017, P = 0.955
Monthly amount of acute headache medication changes, mean ± SD	r = −0.626, P = 0.017^∗	r = −0.499, P = 0.070
Immediate VAS score changes, mean ± SD	r = −0.839, P = 0.0002^∗∗	r = −0.641, P = 0.013^∗

r = correlation coefficient; results represent mean ± standard deviation; ^∗∗statistically significant difference, P < 0.01; ^∗statistically significant difference, P < 0.05.
