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
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
