Help with Odds ratio and confidence interval

Thread Starter Help with Odds ratio and confidence interval Follow 3 hours ago 3h ago I am writing my exam on liver biopsies and the chance for bleeding. One article has researched this and has presented their results in form of odds ratio and confidence interval. I have no idea what they mean. They make a scoring system in order to predict bleeding. They write: "Platelet count was divided into bands of <50000/uL and >50000/uL". Platelet count had a significant predictor of risk (p=0.01) with odds ratio of 3.12 (95% confidence interval of 3.75-29.12)
