U01.06.009 Likelihood ratio 

Read the question carefully and focus on the test’s sensitivity and specificity values. Recall how to calculate likelihood ratios (LR): Positive Likelihood Ratio (LR+) = Sensitivity / (1 − Specificity) → reflects the ability of a test to confirm a disease. Negative Likelihood Ratio (LR–) = (1 − Sensitivity) / Specificity → reflects the ability…
