The method of presenting the results of clinical studies can The hazard ratio would be 2, indicating higher hazard of death from the treatment Hazard ratios differ from relative risks (RRs) and odds ratios (ORs) in that RRs and ORs are cumulative over an entire study, using a defined endpoint, while HRs represent instantaneous risk over the study time period, or some subset thereof Hazard ratios suffer The hazard ratio for mortality from colorectal cancer, comparing intervention with control, was 073 (95% confidence interval 047 to 113) The hazard ratio was less than unity, indicating that the hazard of death in the screening group was less than that in the control group At any time during followup participants in the intervention group
