- Sensitivity = a/(a + c): proportion of all articles with information on glomerular disease in the reference set that are retrieved by the filter (also called recall in information retrieval studies).
- Specificity = d/(b + d): proportion of all articles without information on glomerular disease in the reference set that are correctly not retrieved by the filter.
- Precision = a/(a + b): proportion of all articles retrieved by the filter with information on glomerular disease (also referred to as positive predictive value in diagnostic test terminology).
- Accuracy = (a + d)/(a + b + c + d): proportion of all articles dealt with correctly by filter.
