其他摘要：Ethical and regulatory oversight of research may be suboptimal in low- and middle-income countries. To determine patients’ attitudes and perceptions toward research participation and perceptions of their rights, we recruited 202 participants from hospitals in Egypt, Lebanon, Saudi Arabia and Sudan and asked them to complete a questionnaire assessing attitudes and perceptions. Around 20% believed that doctors sometimes perform research on patients without their knowledge and 35% believed that if participants withdrew from the research they would not receive good medical care. Over 85% believed that they should have rights regarding confidentiality of data, free medical care if injured during the research and asking questions. Almost half believed they have a right to withdraw without penalty and around 75% believed they could make complaints without fear of harm. Those who were illiterate or unemployed were less likely to appreciate their rights compared with their counterparts.
