¹ T ₀ is the initial temperature measured in °C, k is the fractional rate constant, ρ1 is the first-order lag, and ρ2 is the second-order lag.

²Parameter estimates corresponding to the 85-kg class were considered the control. Values presented in the estimate column corresponding to 90 to 105 kg classes are adjustments compared to the parameter estimated for 85-kg class.

³All P values represent to probability that the estimate is equal to zero. For adjusted estimates, significant P values indicate that the parameter estimate for that weight class is different from the 85 kg class.

*The parameter estimate is different from zero (P ≤ 0.05). Lags (ρ1, ρ2) were not adjusted for HCW.
