Scatter plots of mean ICP and ICP wave amplitude in long-term recordings from 4 different patients. These scatter plots exhibit several classes of behavior observed in long-term ICP recordings and illustrate the tendency of short-term linear trends to shift and drift over time in ways that weaken the overall linear correlation between static and pulsatile ICPs.
