Maximum temperature during ICU stay (with each 1°C increase) ¶ | 1.15 | 1.07 | 1.23 | <0.001 |

Antipyretic therapy×Tmax ‡ | 1.33 | 1.12 | 1.58 | <0.001 |
¶ The main effect of Tmax (OR = 1.15) is exponentiation of the slope in the regression model when no antipyretic therapy was given (antipyretic therapy = 1).
‡ The coefficient of the interaction term was the difference of the slope in groups with and without antipyretic therapy. An OR>1 indicates a positive coefficient and steeper slope of the antipyretic therapy group than non-antipyretic group.
