  1. Artifact occurred in 0–24% (mean 2.7%) of the time regarding temperature monitoring periods of 12 h (less than 15% of the time in 24 h) and in 0–4.7% (mean 1.1%) of the time regarding ICP24 monitoring periods. Note that usually the predicted ICP24 was similar to ICP24, and that the predicted interval of ICP24 encompassed ICP24
  2. ICP 24 mean intracranial pressure in mmHg across 24 h after temperature monitoring (80% prediction interval shown between parenthesis), T temperature (in °C), TV temperature variability
