Dear yuvrajkatkar

First of all I would like to tell u that if number of periods or sequences are greater than the treatments which are to be compared, this refers to a higher order crossover design, such a design u mentioned in ur query, model for the crossover design and higher order crossover design are different so point estimate obtained from both designs are not similar so there is no way to obtaine the CV for the 2 X 2 crossover design based on the information obtained from higher order crossover design, you should consider the point estimate and 90% CI from 2 X 2 crossover design to obtained the CV for 2X2 crossover design,
