Determining the percentage of clinical trial participants that are aware of the various aspects of informed consent. A comprehensive search of PubMed, Scopus, and Google Scholar was conducted to find pertinent papers, and reference lists for publications up to October 2013 were manually reviewed. A random-effects model was used in a meta-analysis of study findings to account for heterogeneity.

The analysis examined 135 participant cohorts from 103 research. The proportion of participants in the study who understood the different aspects of informed consent was as follows: 75.8% for the right to withdraw at any time, 74.7% for the voluntary nature of participation, 74.0% for potential benefits, 69.6% for the purpose of the study, 67.0% for potential risks and side effects, 66.2% for confidentiality, 64.1% for the availability of alternative treatment if withdrawn, 62.9% for knowing that treatments were being compared, and 53.3% for p 54.9% of individuals could name at least one risk, while 62.4% of people had no therapeutic misunderstandings. The percentage of participants who understood informed consent did not change over a 30-year period, according to subgroup and meta-regression analyses that revealed covariates that significantly influenced understanding, including age, educational attainment, critical illness, the study phase, and location.
Between 52.1% and 75.8% of participants in clinical trials reported having a thorough understanding of the various aspects of informed consent. To aid participants in having a thorough grasp, researchers could take other measures.
