Table 3 Correlations of Brain Water Content (BWC) with the Area under the Curve (AUC) of ICP-, CPP- and ipsi- and contralateral LCBF in groups 1 – 6

From: Brain edema formation correlates with perfusion deficit during the first six hours after experimental subarachnoid hemorrhage in rats

  1. The numbers on the left of each box resemble the correlation coefficient, the numbers on the left (in brackets) the p-value.There was no correlation of the BWC with the course of ICP- and CPP-values in any group. The BWC showed a significant inverse correlation to the AUC of both the ipsi- and contralateral LCBF-course in animals sacrificed after 180 and 360 minutes.
