A The correlation between serum HBV DNA and nail HBV DNA. No significant correlation was observed (n = 27, r =  − 0.111, p = 0.582). B The correlation between serum HBV DNA and hair HBV DNA. No significant correlation was observed (n = 18, r = 0.285, p = 0.251). C The correlation between nail HBV DNA and hair HBV DNA. There was a weak but significant correlation between nail HBV DNA and hair HBV DNA (n = 48, r = 0.378, p < 0.01). D The correlation between nail HBV DNA and hair HBsAg. No significant correlation was observed (n = 34, r = 0.255, p = 0.145)
