Figure 3. Propofol increased the sweating threshold only slightly; thin upper regression with +95% confidence limits: threshold (degree Celsius)-0.09[propofol(degrees Celsius *symbol* micro gram sup -1 *symbol* ml sup -1)]+ 36.8, r2= In contrast, propofol produced a linear decrease in the core temperature triggering vasoconstriction; middle regression with dashed lines showing +95% confidence limits: threshold (degrees Celsius)=-0.06[propofol (degrees Celsius *symbol* micro gram sup -1 *symbol* ml sup -1)]+ 36.5, r2= Similarly, propofol linearly decreased the shivering threshold; thick lower regression with dashed lines showing -95% confidence limits: threshold (degree Celsius)=-0.65[propofol (degrees Celsius *symbol* micro gram sup -1 *symbol* ml sup -1)]+ 35.6, r2= These regression slopes differ from those reported in Table 3because they were calculated simultaneously from all results, rather than from individual volunteers.
