HI all,
I have to analyse some clinical data. In particular the analysis is a
comparison between two groups of the mean change baseline to endpoint of a
score. The statistician who planned the analysis used the ANCOVA on the mean
change, using as covariate the baseline values of the scores.
Do you think this analysis is correct?
I thing that in this way we are correcting twice. I think that the right
analysis is an ANOVA on the mean change.
Please let me know your opinion
thanks
Paolo
