Echoing @PaigeMiller here, could you provide your definition of "adjusted" mean. I can think of several ways to adjust - subtract baseline, use baseline as a covariate, calculate marginal means to accommodate unequal sample sizes, weight factors in the model by (number of observations, 1/standard deviation, 1/variance, custom weights, any of these in conjunction with the first two). Since I am not really familiar with standards in this field, I don't know how to advise.you.
