The sICH score showed best discrimination among tested models. Also, it was easier for physicians without special training in neurology or radiology to use this scale. With statistical power and ease of use, the sICH score is a very suitable model for risk stratification of spontaneous ICH.

The RF provided the best predictive performance amongst all of the tested models. We believe that the RF is a suitable tool for clinicians to use in predicting the 30-day mortality of patients after SICH.

The ANN provided the best predictive performance among all tested models.
