WebYou can think of the hazard as the slope of the survival curve. The 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.
