Background: Both Glasgow Coma Scale (GCS) and NIH Stroke (NIHSS) are commonly used as serial assessment tools in ICH, however, the NIHSS lacks formal validation this population. Methods: We prospectively collected ICH assessments, imaging, outcome data. Direct comparisons of discrimination were made using GCS on prediction 24-hour poor functional (mRS-3-6) hematoma volume >30cm 3 ROC analysis; c statistics calculated compared with DeLong test. Results: 672 patients (mean age 62±14 years; 56% men; median score = 1, IQR 0-2; 7cm , 2-19) included analysis. Median 8 (IQR 3-18) 15 7-15) respectively. correlated strongly to (r -0.773; p<0.001). (c statistic: 0.91; 95%CI: 0.89-0.93) discriminated better than 0.78; 0.75-0.81) for (DeLong p<0.001; Figure 1A). 0.82; 0.78-0.86) also 0.73-0.83) large p=0.029; 1B). Conclusions: The has greater discriminative power identify outcomes volumes.
