Thanks for this video series, it’s really helpful. I just wanted to feedback that your BNP/Echo question regarding specificity had incorrect answers only. Specificity is true negative results / total actual negatives, i.e. 45/(54+45). It may mislead candidates sitting the exam who have learnt the correct definition. I suspect this may just be a typo.
That’s NPV, sensitivity is TN/TN+FP
