Figure 2: Serum levels of HCMV-encoded miRNAs in CHB patients arranged into training and validation sets.

(a) Absolute concentrations of 13 HCMV-encoded miRNAs in training set samples (n = 10). (b) Scatter diagram of the absolute concentration of HCMV-miR-US4-1 in the samples of training set (P = 2.13 × 10−6). (c) Scatter diagram of the absolute concentration of HCMV-miR-UL148D in the training set samples (P = 1.3 × 10−4). (d) Absolute concentration of HCMV-miR-US4-1 and HCMV-miR-UL148D in the samples of testing set (n = 18). (e) Scatter diagram of the absolute concentration of HCMV-miR-US4-1 in the testing set (P = 6.65 × 10−13). (f) Scatter diagram of the absolute concentration of HCMV-miR-148D in the testing set (P = 7.26 × 10−6). The data are presented as the mean ± SEM. Horizontal lines indicate medians P values calculated by a 2-sided Student t-test. *P < 0.05; **P < 0.01.
