CRP and hematoma: We analyzed the correlation of serum IL-12 levels with other clinical features using Spearman correlation coefficient in 209 cases ICH patients, and the results showed that serum IL-12 level was closely related to admission NIHSS scores (r = 0.535, P < 0.001, Figure 1), hematoma volume (r = 0.608, P < 0.001, Figure 2), serum CRP levels (r = 0.561, P < 0.001, Figure 3), and serum TNF-α levels (r = 0.533, P < 0.001, Figure 4) in 209 cases ICH patients (Table 2).
