ANOVA

#1
I am conducting a research to test a difference between two treatment methods. I received a query from a statistical reviewer that I cannot understand: “The repeated measures ANOVA is appropriate for this analysis however as currently described between group difference in the amount of change between time points is not able to be examined. Including a time by group interaction would allow the authors to compare the change in outcome and CC distance from one time point to the next. This would help account for the fact not everyone starts with the same Constant score or CC distance, so comparing the means at a single time point could be misleading. I appreciate that the data appears very balanced due to the randomization however the amount of change between the groups should be considered.”
Can any one help me to understand what is needed??

You should have included a description of what the reviewer is referring to
(i.e. what you did in your statistical analysis). Anyway - he suggests that you
conduct a mixed ANOVA (repeated-measures ANOVA with an additional
group factor). The interaction between factor "time" and factor "group"
represents whether the change over time was different for the respective
groups.
