Heatmap of the correlation coefficients between each brain region associated with FC ([7,10], [77,120], [106,116], [106,120], [115,120], [128,136]) and each scale (LKES, LMS, QOD-NS, TDI, and PHQ-2) in the CRSwOD group. Purple indicates positive correlation, white indicates negative correlation, and the darker the color, the stronger the correlation. A diagonal line set to 1.00 represents a full positive correlation between the variable and itself, and a display of 0 indicates that no correlation was analyzed between these two variables. Correlation coefficients with an asterisk (*) indicate statistical significance (p < 0.05). FC functional connectivity, LKES nasal endoscopy Lund–Kennedy score, LMS sinus computed tomography (CT) Lund–Mackay score, NBS network-based statistic, ROC receiver operating characteristic, rs-fMRI resting-state functional magnetic resonance imaging, PHQ-2 Patient Health Questionnaire-2, QOD-NS Questionnaire of Olfactory Disorders-Negative Statements, TDI threshold, discrimination, and identification in Sniffin Sticks tests.
