a) All tested samples: 882 samples from 115 patients were tested for CMV. The proportions of all tests are shown by the time (in months) they were drawn after transplant; each bar depicts the percentage of tests that were negative by both tests (CMV Negative, light bar), or positive by at least one test (CMV Positive, dark bar). The sample tested the longest time after transplant was drawn at 184 months post-transplant.
b) Positive tested samples: 95 samples from 31 patients tested positive for CMV. The proportions of positive tests are shown by the time drawn after transplant. The positive sample observed latest after transplant was drawn at 155 months post-transplant.
