Hazard ratios do not reflect a time unit of the study. The difference between hazard-based and time-based measures is akin to the difference between the odds of winning a race and the margin of victory. [3] When a study reports one hazard ratio per time period, it is assumed that difference between groups was proportional.
Formula Value Absolute risk increase ARI EER − CER: 0.1, or 10% Number needed to harm: NNH 1 / (EER − CER) 10 Relative risk (risk ratio) RR EER / CER: 1.25 ...
This interpretation of the baseline hazard as "hazard of a baseline subject" is imperfect, as the covariate being 0 is impossible in this application: a P/E of 0 is meaningless (it means the company's stock price is 0, i.e., they are "dead"). A more appropriate interpretation would be "the hazard when all variables are nil".

A hazard quotient is the ratio of the potential exposure to a substance and the level at which no adverse effects are expected. If the Hazard Quotient is calculated to be less than 1, then no adverse health effects are expected as a result of exposure. If the Hazard Quotient is greater than 1, then adverse health effects are possible.
