Figure 1. Treatment with hydrogen-rich saline has no long-term effects neither on mortality rates nor on SAH grade in SAH models. (a) Mortality rates in the sham group (5.6%), SAH group (27.8%), and the SAH + HS group (16.7%). No significant differences between the three groups. (b) SAH grade scores in the sham group, the SAH group, and the SAH + HS group, which showed no significant differences (one-way analysis of variance [ANOVA]).

SAH: Subarachnoid hemorrhage; HS: hydrogen-rich saline.
