How to Interpret Confidence Intervals in Cancer Studies?
Interpreting confidence intervals involves understanding both the point estimate and the range. For example, if a study on a new chemotherapy drug reports a hazard ratio of 0.75 with a 95% CI of 0.60 to 0.90, it means that the treatment reduces the risk of death by 25%, and we are 95% confident that the true hazard ratio lies between 0.60 and 0.90.
