Fig. 6

Intraindividual differences in (A) total body heat and (B) NRS score between treatment with forced air warming and warming using a fleece blanket. The distribution of heat and NRS score, respectively, for a given time are displayed as boxplots with additional means (dashed lines). Positive values indicate higher values with forced air warming. The dotted red line indicates indifference between the two methods. Individual data points as grey dots. The grey shaded region shows the time period of warming intervention. Asterisks indicate time points of statistically significant differences between methods
