Mood symptoms, cognitive function, and changes of brain hemodynamics in patients with COVID-19: A functional near-infrared spectroscopy study

Figure 6 Scatter maps showing the correlations between the scores of Patient Health Questionnaire-9 and network measures and correlations between the scores of General Anxiety Disorder-7 and network measures. The black dotted line indicates the Linear fitting trend. A: Correlation between Patient Health Questionnaire-9 (PHQ-9) and global efficiency; B: Correlation between PHQ-9 and local efficiency of dorsolateral prefrontal cortex; C: Correlation between PHQ-9 and Short-II (intrahemispheric connectivity between different regions of interest); D: Correlation between General Anxiety Disorder-7 (GAD-7) and global efficiency; E: Correlation between GAD-7 and local efficiency of dorsolateral prefrontal cortex; F: Correlation between GAD-7 and Short-II. All correlations were calculated at 0.5 threshold.
