| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Single Nucleotide Polymorphisms (SNPs) Associated With HBeAg Seroconversion or Hepatitis B Surface Antigen (HBsAg) Clearance ≥24 Weeks Post-Treatment in HBeAg-Positive East Asian (CN) Population: Additive Model | Single blood sample ≥24 weeks post-treatment | Genome-wide association study (GWAS) approach was used to evaluate the association of SNPs with treatment response. HBeAg seroconversion was defined as the loss of HBeAg and detection of the antibody to HBeAg (anti-HBe). HBsAg clearance was defined as the loss of HBsAg, with or without detection of the antibody to HBsAg (anti-HBs). Associations with treatment response were analyzed using logistic regression and adjusted for covariates. Markers were coded according to additive models of inheritance. Markers surpassing p-value thresholds of p\<10\^-5 and p\<5x10\^-8 were considered suggestive and genome-wide significant, respectively. Larger beta coefficients correspond to greater likelihood of treatment response. |
