Fig. 5

Significant relationships between intracranial pressure (ICP)-derived metrics and quantitative measures of computed tomography features. a Mean ICP versus total lesion volume. b Peak-to-peak pulse amplitude of ICP (AmpICP) versus total lesion volume. c Pulse shape index (PSI) versus total lesion volume. d) PSI versus the extent of midline shift. Individual observations (dots) are grouped over total lesion volume (bin width 50 cm3) or the extent of midline shift (bin width 5 mm). Dashed line shows the estimated linear regression line. Values above the plots indicate the Spearman correlation coefficient and its p value. a.u.—arbitrary units
