Table 2
Variance between temperature time-points. The variance at each time-point describes the difference in Celsius from the time-point baseline/reference “5 am–7 am”. The total circadian variance is calculated by a SAS type 3 tests of fixed effects. NS = Not significant.

Figure 1
Circadian temperature variance. Figure 1 illustrates data from Table 2 with the measured median circadian temperature variance (narrow bold line) with lower and upper temperature reference levels (dashed lines). The thick bold line is the normal known physiological circadian core body temperature and its temperature variance during the measured time period in relation to the time-point reference 5 am–7 am. The y-axis illustrate temperature levels in Celsius and the x-axis illustrate time interval for the collected temperature period.
Figure 2
Mean forehead temperature. The mean forehead temperatures for each time interval are shown with a dashed line. The bold line illustrates normal known physiological core body temperature at each time interval. The y-axis illustrate temperature levels in Celsius and the x-axis illustrate time interval for the collected temperature period.
