Dear Sir For BE studies do not use the t-test paired data.if you need any results in BE study please send me your data in the following email mahmohsen111yahoo.com Edit: Full quote removed.

Salam Mahmoud, ❝ Dear Sir I assume that Maryam is not a Sir. ❝ For BE studies do not use the t-test paired data. We don’t know the design of Maryam’s study. What if it was not a crossover? Examples where a paired t-test would be correct indeed:

❝ We don’t know the design of Maryam’s study. ❝ @Maryam: What is the structure of you data? I don’t speak SAS but which error did you get? Hi sir Maryam is not a sir thanks for your answer, my structure is a crossover study! actually I want to calculate 90% CI for BE parameters of test/reference! and I want to evaluate the effect of period, sequence, subject and treatment! I know how calculate these by formulations but I need a software to calculate these! would you please to guide me in this problem? thanks Edit: Full quote removed.

@Maryam For a 2x2 cross-over, the following code will get you everything you need (ods outputs LSMeandiffCL, LSMeans, AltErrTests and OverallANOVA) proc glm data=replicate; Formulation and Period p values come from OverallAnova, while sequence p value from AltErrTests. This code in principle will fit both EMA and FDA requirements for a 2x2 design. Although FDA requests subject within sequence as random effect, this will not change the result. |

Hi David, ❝ <nitpicking> Why are you calling a data set of a 2×2 crossover ❝ I would remove adjust=t . There is nothing to adjust in a 2×2 crossover.

Hi Helmut, The reason for "Replicate" as the dataset name is because I took the code from the EMA Q&A Guideline and adapted it - but forgot to remove the misleading name I agree with you regarding the adjusment question. Nevertheless, as far as I understand the parameter does nothing if you leave it on the code. |

❝ For BE studies do not use the t-test paired data. Hi sir thanks for your answer. your are right! t-test paired does not use for BE studies. By SAS and ttest I want to calculate 90% CI for pharmacokinetics parameters of test/reference. would you please to help me to calculate 90% CI for pharmacokinetics parameters of test/reference by any softwares? can I use this calculation by SPSS? thanks Edit: Full quote removed.
