Generally uncertain

Applies to intervention studies

If going to intervene into someones situation, shouldnt be making a situation worse of than they would be if they werent in the study

A

• Lack of consideration of the harms to ‘participants’. Doctors acted on own views as to what was best
• information was withheld from participants. Participants
weren’t asked if they wanted to participate
• poorer patients with less social support
• lacked scientific integrity. The investigator interpreted results in accordance with what he wanted to find
• The institution failed to hold it’s members accountable to the expected ethical standards. This showed the need for external oversight

  • Transparency
  • That all people are considered of equal worth

• inclusion and exclusion
conditions for participants are fair. People should not be excluded on the basis of sex, ethnicity, national origin, religion, education or socioeconomic status, except where such exclusion or inclusion is essential to the purposes of the study.
• Funders and researchers should support and design research that could help reduce inequity.
