From: Clinical features of Parkinson’s disease patients are associated with therapeutic misconception and willingness to participate in clinical trials

Statements Agreement “cannot say” Disagreement
n % n % n %
Persons diagnosed with PD should be asked to participate in CTs 559 83 81 12 32 5
If patients refuse to participate in CTs, new treatments will not become available 417 63 140 21 108 16
Research results should be discussed with research participants 634 95 17 3 13 2
I think it is important that all clinical trials’ results be published and health-care professionals gain access to them 620 93 29 4 19 3
I would like to receive as much information as possible about the trial and the new drug before I make a decision about participation in a CT 561 83 57 9 54 8
New PD medications are usually studied in comparative trials (an old drug is compared to a new substance or a placebo); I would like to participate in this kind of CT 336 50 177 26 157 23
I would participate in clinical trials because it would enable me to help other patients with Parkinson’s disease 567 86 64 10 32 5
I would participate in a CT in which there is a possibility of receiving a placebo (placebos do not contain any active ingredient) 274 42 145 22 238 36
I would participate in a CT if it involved a significant risk of severe adverse effects (adverse effects that could lead to prolongation of hospitalization or cause permanent disability) 34 10 100 15 492 75
