Concern with Multiple mixed repeated measure analysis/ Ancova I can't understand what type of graphical analysis is this in the attached figure.

The statistical analysis conducted was a MMRM or ANCOVA?  How can they combine control and treatment in one line (MMRM one)
[the picture is from donanemab study)


Assuming the following:
MMRM = Mixed Model for Repeated Measures, and
DPM = Disease Progression Model

The statistical analysis conducted was a MMRM or ancova ?

It is a MMRM. There are presumably repeated measures within participants / subjects so a mixed model would be a fairly typical approach.

How can they combine control and treatment in one line (the MMRM one) ?

I don't know what you mean by combine them "in one line" ? For example, the first MMRM point estimate in the figure, for iADRS Score, is approximately 20. Since this is greater than zero, it means that the treatment is protective.
