SCG2 and hematoma: Those significant factors on univariate analysis were incorporated in multivariate logistic regression analysis, and then we found that serum secretoneurin levels (odd ratio, 1.061; 95%CI, 1.004–1.122; P = 0.037), GCS (odd ratio, 0.639; 95%CI, 0.490–0.832; P < 0.001) and hematoma volume (odd ratio, 1.079; 95%CI, 1.033–1.127; P < 0.001) were the independent predictors of poor outcome.
