❝ ❝ ... Power is based on assumptions. If those assumptions are wrong...❝

❝ And this is not post hoc power but ad hoc power/sample size estimation as always necessary in the design step of a study.

Although the results of this trial suggests a greater sample size would be needed in order to repeat the same trial (I mean, shit happens, right?), the initial assumptions can be supported.

Thank you Maestro and d_labes, your points are clear.
