PharmD_Rodriguez said:Relative and absolute effects need reading together.
PharmD_Rodriguez has the substance of this right. The condition it depends on is worth stating. The gap between trial results and real-world results is consistent and it is not fraud. Trial participants get titration by protocol, scheduled contact, free drug and dietetic support; removing that infrastructure costs a few percentage points every time it has been measured. When your own curve sits below the published mean, that is the likeliest explanation before anything about you or your material.
Ask again with the specifics and you will get a better answer than this one.
