With incorporation of the above seven variables into the multivariate linear regression model, the factors of independent relation to mRS were NIHSS scores (beta, 0.141; 95% CI, 0.069–0.214; VIF, 3.077; p = 0.011), hematoma volume (beta, 0.033; 95% CI, 0.004–0.061; VIF, 3.682; p = 0.014), and serum MLKL levels (beta, 0.707; 95% CI, 0.487–0.927; VIF, 1.742; p = 0.023). The gene discussed is MLKL; the disease is hematoma.
