To provide methodological guidance on selecting and interpreting statistical tests for treatment group comparisons in cancer clinical trials when competing risks are present.
Compared two primary analytic frameworks for competing events: cause-specific hazard functions (evaluated via log-rank or related tests) and cumulative incidence functions.
Evaluated test performance and behavior using simulation studies and empirical examples from cancer clinical trials.
Inferential results and statistical conclusions can differ considerably between cause-specific hazard tests and cumulative incidence tests for the same cause-specific endpoint.
Neither metric is universally superior; the appropriate analytical choice depends on the specific clinical question, and reporting both metrics often provides a more complete assessment of treatment effects.
