FIGURE 2.
Scatter plot of the correlation and regression between Hamilton Depression/Anxiety (HAMA/HAMD) scores and clinical scores and serum homocysteine levels. A significant positive correlation (r = 0.477, p < .01) was observed between the clinical severity score and HAMA scores in patients with N2O‐related neurological disorders (a). There was a significantly positive correlation (r = 0.324, p < .01) between the serum homocysteine levels and HAMA scores (b). A significant positive correlation (r = 0.442, p < .01) was seen between the clinical severity score and HAMD scores in these patients (c). Serum homocysteine levels had significantly positive correlation with HAMD scores (r = 0.346, p < .01) in our patients (d)
