temperature for the continuous and intermittent exposure was compared with respective
findings on the no-exposure day. Since the temperature measured before the experiment might
affect the temperature during all exposure types, it was considered as a covariance. The adjusted
tympanic temperature for group on the day of continuous and intermittent exposure were found
to differ significantly from respective time periods during the sham day (Table 1).
