Number of patients tested by each method who had laboratory evidence of Lyme disease and who were positive (black bars) or negative (gray bars) by each test or test combination compared with the total number of enrolled subjects for whom each test was conducted. The percentages of patients who tested positive out of the total with laboratory evidence of Lyme disease who had that test or test combination are shown on the bars. The numbers of patients with no laboratory evidence of Lyme disease are shown with the white bars. The 95% CI for each sensitivity determination is indicated on the right side of the panel.
