accuracy is probably not the best term to use here, since it is involves a combination of true positives and true negatives..... (a + d) / (a + b + c + d). for cystic fibrosis.... the sweat chloride test is more sensitive (i.e., low false negative rate), but the genetic testing is more specific (i.e., less false positive rate). both influence the accuracy of the test in a different way.


here a couple brief youtube videos explaining how accuracy is used as a measure of test performance...
accuracy - definition and equation
accuracy - how to calculate it

02 is the correct answer. smoking cessation has been shown to decrease the rate of decline in pulmonary function, but only 02 has been shown to increase survival.

I used UptoDate whenever there was a difference between mtb and UW. UW was always right btw.
