Figure 2

Scatter plots of CSFP wave amplitude during the opening period and during lumbar infusion for the two categories of over-night pulsatile ICP (mean ICP wave amplitude either < 4 mmHg or ≥ 4 mmHg during the period 11 p.m. to 7 a.m.) a) Shows the pulsatile CSFP (mean CSFP wave amplitude) during the opening phase after lumbar puncture, and (b) during the phase of lumbar infusion (15 ml over 10 min; 1.5 ml/min). Dotted lines denote different targets for CSFP wave amplitude during the opening period and during lumbar infusion. Significant differences between groups were tested with one-way ANOVA.
