ANCOVA, threshold was set at P < 0.025 (AlphaSim-corrected, cluster size > 2,025 mm3 voxels); Two-sample t-test, threshold was also set at P < 0.025 (AlphaSim-corrected, cluster size > 162 mm3 voxels). X, Y, Z, coordinates of primary peak locations in the MNI space. rCBF, regional cerebral blood flow; MNI, Montreal Neurological Institute space; BA, Brodmann area; R, right; ANCOVA, analysis of covariance; DA, depressed asthma; NDA, non-depressed asthma; HC, healthy controls.
