Hazard ratios in cancer clinical trials--a primer Nat Rev Clin Oncol. because a hazard ratio lacks dimensions it can only inform the reader about the reliability and uniformity of the data. It does not provide practitioners with quantitative values they can use, nor does it provide information they can discuss with patients. Motivated by a non-scientific poll of oncologists in training and NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. Odds Ratio, Hazard Ratio and Relative Risk Janez Stare1 Delphine Maucort-Boulch2 Abstract Odds ratio (OR) is a statistic commonly encountered in professional or scientific medical literature. Most readers perceive it as relative risk (RR), although most of them do not know why that would be true. But since such perception is mostly correct, there is nothing (or almost nothing) wrong with that The hazard ratio for breast cancer was 0.91 (95% CI, 0.83–1.01). It was noted, however, that the women in the intervention arm with the highest baseline fat intake had a greater reduction in breast cancer (P for trend = 0.04) (35). The low-fat diet group had a statistically significant increase in sex-hormone-binding globulin as well as lower levels of serum estradiol. The hazard ratio for breast cancer was 0.91 (95% CI, 0.83–1.01). It was noted, however, that the women in the intervention arm with the highest baseline fat intake had a greater reduction in breast cancer (P for trend = 0.04) (35). The low-fat diet group had a statistically significant increase in sex-hormone-binding globulin as well as lower levels of serum estradiol. The hazard ratio quantifies the difference between the hazard of two groups and it is calculated as the ratio between the ratios of observed events and expected events under the null hypothesis of no difference between the two groups. For ER, the hazard ratio was initially less than 1.0, indicating a good effect on prognosis, but increased at later times to values greater than 1.0, indicating a bad effect on prognosis. In contrast, the hazard ratios for tumor size and S-phase were initially high and decreased asymptotically toward 1.0 over time. Analysis of p53 expression in a subset of cases yielded qualitatively similar
