“True art is to hide art” ~ Anon (often misattributed to Virgil)
“True statistics is to hide statistics” ~ Methods Appraisal
A well designed and executed clinical trial only requires a simple analysis. A complex, aggressive analysis can be indicative of poor design or a trial gone astray.
A complex analysis usually requires the statistician to speak (exhaustively) on behalf of the data (left).
A skilfully designed, well executed study requires simple analysis allowing the data to speak for itself (right).

…the strength of the evidence is inversely associated with the dependence on statistical manipulation. (Hall, D; 2006)
