The following tables relate treatment (standard, new)) and outcome (success, failure)) separately for two facilities (A, B). Facility A Success Failure New 95 5 Standard 500 500   Facility B Success Failure New 100 900 Standard 5 95   (3pts) For each facility separately, calculate the odds ratio for “success” when comparing the two treatments. You may take the “standard” treatment as the baseline. (2pts) Find the marginal table between treatment and outcome, and calculate the odds ratio for “success” from this table. (3pts) Comment on the difference between the results in parts A and B. Which treatment do you think is better and why?
