You are asked to review the clinical notes of 100 patients at your practice who have Knee Osteoarthritis and a further 100 patients who have normal knee radiographs. You are looking at their BMI results to determine whether being clinically obese affected the outcome. Of the 100 patients with radiographic evidence of Knee Osteoarthritis, 24 of these patients were clinically obese based on their BMI. Of the 100 patients with normal knee radiographs levels, 16 were obese.

What is the odds ratio of being obese? All calculations are rounded to 2 decimal points.
