  • a HBI, hepatitis B virus infection; HBV, hepatitis B virus; anti-HBs, antibody to hepatitis B virus surface antigen; anti-HBc, antibody to hepatitis B virus core antigen. Statistical significance was determined by Fisher's exact test. For teenagers' HBI statuses, overall P = 0.46 for ① and ⑤, P = 0.14 for ②, ③ plus ④, and ⑤, P = 0.28 for ②, ③, ④, and ⑤, P = 0.63 for ② plus ③, ④, and ⑤, and P = 1.00 for ② plus ⑤ and ③ plus ④. For teenagers' anti-HBc statuses, overall P = 0.04 for ① and ⑤, P = 0.05 for ②, ③ plus ④, and ⑤, P = 0.02 for ②, ③, ④, and ⑤, P = 0.02 for ② plus ③, ④, and ⑤, and P = 0.02 for ② plus ⑤ and ③ plus ④.
