Figure 1
Awareness and insights of respondents towards clinical trials. Participants’ awareness of the term ‘clinical trial’ and prior experience with clinical trial participation, illustrating the proportion of participants who had previously heard of the term and those who had ever participated in a clinical trial. Insights regarding clinical trials and future willingness to participate also were reported.

Figure 2
Motivators for participation in clinical trials. Self-reported motivators to participate in clinical trials reported mainly as help in advancing science and helping other patients.

Figure 3
Barriers for participation in clinical trials. Self-reported barriers for participating in clinical trials are safety concerns and family commitments.

Figure 4
Willingness to participate in clinical trials according to respondents’ characteristics. Univariate analysis showed that main determinants of willingness to participate in future clinical trials are education and awareness of the term ‘clinical trials.’
