TPH2 and stroke disorder: In multiple logistic regression analysis, PSD was related to the National Institutes of Health Stroke Scale (NIHSS) score at admission (95% confidence interval [CI]: 1.047–1.230, p < .01), modified Rankin scale score at 3 months (95% CI: 0.135–0.848, p < .05), and TPH2 rs4641528 C allele (95% CI: 1.039–5.631, p < .05), whereas PSEI was associated only with the NIHSS score at admission (95% CI: 1.053–1.259, p < .01) and the TPH2 rs4641528 C allele (95% CI: 1.029–11.678, p < .05).
