Hi BDAZ,

You said," There are always patient drop outs, especially in long clinical trials. Some of it is because patients die, but for most cases it is some kind of non-fatal adverse event that leads to patient voluntary discontinuation/withdrawal of consent or disconti"nuation at the advisement of the physician."

Can you please give this novice a few examples of non-fatal adverse events? Safety issues, I will assume are out of the equation. 

TIA,
