 90% CI of ratio of SDs for NTI drugs [RSABE / ABEL]

Dear all,

As we know for NTI drugs guidelines Warfarin has suggested that use both (1) scaled and unscaled ABE, in addition to that (2) calculation of 90% CI of ratio of within subject standard deviation of test to reference product.

here my problem is (2). i don't know how to calculate (2). but i tried it with 'COVPRMS' of 'PROC MIXED' from normal ln transformed data (not from ilat, dlat). i calculated within subject standard deviation for test and reference using 'estimates' in 'COVPRMS'. now i just want to know am i doing it in the correct way or not?

Thanks and Regards,
Satish.
