❝ Really? If your ratio and CV are just 0.02% (!!) worse, your power would already be <80%. Remember that outcomes of pilot studies are estimates, not set in stone. Planing for 80% power – hoping for exactly matching the pilot and face not a single drop-out in such a large study – is gambling as well.*

Its real.

❝ * In the pivotal study PE ↓ 83.82%, CV ↑ 27%, and you had 14 drop-outs…

very correct.

Also confirm me if i do redosing study and it confirms the outlier. should i present the data without that subjects as discussed by John.
