The formula for translating a hazard ratio to a probability is:probability = (hazard ratio) / (1 + hazard ratio). So there is a 75% chance that the the treated patient will heal before the control patients.

WebThe CEE/MPA arm of the WHI showed a hazard ratio of 1.26 (confidence interval [CI], 1.0-1.56). The degree of risk, however, is quite controversial. Various studies have shown that HT is associated with an increased risk of breast cancer, but others have not concurred. Web16 hours ago · The median follow-up of 38 months (range, 3–78 months). There were no statistically significant differences in tumor location, T stage, lymph node status, radiochemotherapy, and TNM stage between the low and normal preoperative AGR groups. The proportion of patients in the low AGR group with female (30%), high age (52.1%) … WebThe hazard ratio is defined as the ratio of two hazard functions, \(\lambda_1(t)\) and \(\lambda_2(t)\), corresponding to two treatment groups. Typically, we assume proportional hazards, i.e., \(\Lambda= \dfrac{\lambda_1(t)}{\lambda_2(t)}\) is a constant function independent of time.
