Basic Confidence Interval Question using IVD Performance add-in

marcstein

Sorry for asking what is likely an overly simple question, but...

 

I want to express Sensitivity and Specificity values at a 95% CI. When I run IVD Performance I see the following values:

 

Estimated, Lower 95% CI, and Upper 95% CI

 

In my particular model the Estimated.Sensitivity is 0.982, Lower.Sensitivity is 0.959, and Upper.Sensitivity is 0.992

 

If I want to represent the 95% CI value, is it the Estimated value?

 

Thanks in advance!

The estimate of the sensitivity based on your sample of data is available as a point estimate and a confidence interval estimate. The point estimate is 98.2% The 95% confidence interval estimate is 95.9%-99.2%.
