Fig. 3From: Brain regions involved in fractional amplitude of low-frequency fluctuation in cluster headache patients: a resting-state functional MRI studyCorrelation analysis of clinical characteristics and mean fALFF values. The fALFF value of the left lenticular nucleus was negatively correlated with the visual analog scale score (A) in the L-CH group, but that of the right inferior parietal lobule positively correlated with patient age (B) in the R-CH groupBack to article page
