logistical limitations = opportunities? [General Statistics]
Dear all
Advantage of interim stats: with some luck you'd even need to include fewer subjects than first feared.
Disadvantage: with some bad luck you'd even need include more than first feared due to analyses conducted at adjusted significance levels. Furthermore an interim analysis takes time (you have to perform the bioanalysis of the PK samples before starting the second group). For a generic company this is a strong argument.
If you follow Helmut's suggestion ensure that bioanalysis will not start before the subjects of the second group are enrolled.
Kind regards
Dan
