Table 4 Concordance of Antibody Identification Among Designs when Applied to Example Data. Results of implementing the designs on resampled example data, comparing the case control design and two-phase group testing design with group sizes 5, 10, and 20. Note that the standard group testing design will identify the same significant antibodies as the case control design, so results are not explicitly listed for simplicity

From: Using group testing in a two-phase epidemiologic design to identify the effects of a large number of antibody reactions on disease risk
