The results of ROC analysis in PSD and MDD groups indicated that the protein and mRNA levels of GDNF could serve as general distinguishing models with the AUC at 0.797 (95% CI, 0.696~0.898, P < 0.001) and 0.831 (95% CI, 0.744~0.918, P < 0.001) respectively. Abbreviations: ROC, receiver operating curve; PSD, post stroke depression; MDD, major depressive disorder. GDNF, glial cell line-derived neurotrophic factor; AUC, area under the curve.
