TABLE 2.

Two-sample t-test differences between AR patients and HCs using the ALFF method.

Brain region	R/L	No. of voxels	MNI (x, y, z)			Peak
AR < HC
PCUN	L	105	0	–66	36	–5.1729
AR > HC
ACC	L	61	–6	39	–6	4.7576

AR, allergic rhinitis; HCs, healthy controls; ALFF, amplitude of low-frequency fluctuation; FWE, family-wise error; R/L, right/left hemi-cerebrum; MNI, Montreal Neurological Institute; PCUN, precuneus; ACC, anterior cingulate cortex.

p < 0.01, cluster level; p < 0.05, FWE correction.
