$F=\mathrm{ANOVA}\left(\text{EOT}=b_0+b_{\text{Therapy}}\text{Therapy}+b_{\text{Age}}\text{Age}+b_{\text{T0}}\text{T0}+b_{\text{Sex}}\text{Sex}+b_{\text{sex:therapy}}\text{sex:therapy}+b_{\boxed{\text{therapy:sex:T0:age}}}\boxed{\text{therapy:sex:T0:age}}+b_{\boxed{\text{therapy:sex:T0}}}\boxed{\text{therapy:sex:T0}}+b_{\boxed{\text{therapy:sex}}}\boxed{\text{therapy:sex}}+b_{\boxed{\text{therapy:T0:age}}}\boxed{\text{therapy:T0:age}}+\epsilon \right)$

• Correctly identified the problem as a group comparison with covariate adjustment.
• The correct covariates $\text{T0}+\text{Age}$ were included in the model.
• The correct strata $\text{Sex}$ were included in the model.
• The distractor variable(s) $\text{FU}$ were erroneously included in the model.
• The statistical model should not include the treatment-by-covariate interactions$\text{therapy:T0:age}+\text{therapy:sex}+\text{therapy:sex:T0}+\text{therapy:sex:T0:age}\text{.}$
• The $F$-ratio for $\text{Therapy}$ has been reported.
