Fig. 2.

Wuhan-Hu-1 IgG levels 2 weeks after the second SARS-CoV-2 vaccine dose (T2) in patients with CLD according to demographic and clinical characteristics, and type of vaccine.

Violin plots representing IgG levels. Black horizontal lines indicate the median, and grey dotted lines indicate the IQR. For comparisons between two groups, parametric or non-parametric data was analysed using Student’s t test or the Mann–Whitney test, respectively. For multiple comparisons, parametric or non-parametric data were compared using ANOVA or the Kruskal–Wallis test, respectively, followed by Bonferroni’s or Dunn’s post hoc test. ∗p <0.05; ∗∗p <0.01; ∗∗∗p <0.001; ∗∗∗∗p <0.0001. CLD, chronic liver disease; MRFLD, metabolic-related fatty liver disease.
