Correlation between clinical signs / laboratory markers and PCR results. This table shows the percentage (number) of infants with samples in each Cq range and number of clinical signs (1 to 6) as well as percentage (number) of infants with abnormal laboratory markers and the p-values as calculated by two-tailed Fisher’s exact test.
