Hi, Helmut!

» (i.e., same site, same procedures, all subjects randomized before splitting, same batches of T and R, short time interval between groups, blahblah).

Many times the approach with resigning from testing group effect based on justification in protocol that volunteers undergoes the same procedures, take the same batch of drug etc., was fine and very helpful for many protocols. But. Recently one clinic has used two slightly different types of menu for two groups. Volunteers ate the same food in period 1 and 2. Could this situation lead to necessity to test group effect since not the same procedures were implemented to two groups or this difference has too little weight?

Best regards
