Odds ratio the ratio of cross products This is not true for relative risk Switching the rows or columns inverts the odds ratio For example, the odds ratio for no cough given a history of bronchitis = (247/26)/(1002/44) = 0417 = 1/2397 This is the reciprocal of the OR for cough There are only two possible odds ratios, as switching bothThe 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 vs Risk Ratios (or Relative Risk) Hazard ratio is frequently interpreted as risk ratio (or relative risk), but they are not technically the same However, if that helps you to understand hazard ratio then it is OK But keep in mind HR is not RR One of the main differences between risk ratio and hazard ratio is that risk ratio does not care about the timing
