Lithium therapy has been associated with a reduction in the risk of suicidal behavior, defined as a suicide attempt or completion (2). However, there exists limited evidence to suggest that planning for a suicide, a subtype of suicidal ideation, is attenuated by lithium therapy. In a recent consensus statement, experts argued that combining suicidal thinking and behavior should not be a standard endpoint for randomized controlled trials (3), and ideation per se does not have a well-documented biological basis. Oquendo et al. emphasize that they calculated power to detect a relative risk of 5 or greater, which compares favorably with the relative risks associated previously with not taking lithium versus taking lithium (relative risk=4.91, 95% CI=3.82–6.31) (2). However, sufficient power is only derived from including individuals with a plan for a suicidal act. Can the authors provide a power analysis only for suicidal behavior as an outcome, and discuss conclusions based on the outcome of that analysis?
