Hello

I need to compare my “control” group with all other groups that received a dietary supplement with three different ratios. Now I want to compare my control group with the other three groups using the Orthogonal contrast in SAS.

I have a confusion about the “Treatment order”. Can someone help me what will be the correct “Treatment order” to compare the control group with all other groups?

you need the original Dunnett (1955) test (search online for full reference)
