Which best describes a favorable risk-benefit ratio in TCPS 2?

• A. Benefits to participants or society justify the risks; risks are minimized and meaningful benefits anticipated.
• B. Risks are minimized but benefits are not anticipated.
• C. Benefits outweigh risks without any safeguards.
• D. Risks and benefits are not considered together in planning.

Answer: (A)

In TCPS 2, a study earns a favorable risk-benefit balance when the potential benefits to participants or to society justify the risks, and those risks are minimized through appropriate safeguards. This means researchers design the study to reduce harm as much as possible and to ensure that there is a meaningful expectation of benefits—whether direct benefits to participants or societal benefits from the knowledge gained. It’s not enough that benefits might exist or that risks are outweighed by some vague gain; there must be a clear plan to minimize risk and a reasonable expectation that beneficial outcomes will occur.

That’s why the best description is: benefits to participants or society justify the risks, and risks are minimized with meaningful benefits anticipated. The other options fall short because they ignore anticipated benefits, omit safeguards, or separate risk and benefit planning instead of integrating them in the study’s design and approval process.
