Factors associated with refusal or acceptance of older patients (≥ 65 years) to provide consent to participate in clinical research in cardiology: a qualitative study.

Structural conditions, such as personal benefit from trial participation, or logistic barriers to participation, seem to affect both accepters and refusers in the same manner.
