Fig. 5. Histologic responses between patients with GerdQ ≥8 and GerdQ <8. The degrees of basal cell hyperplasia (p=0.043) and papillary elongation (p=0.048) were reduced significantly patients with GerdQ ≥8. The papillary elongation was reduced significantly in patients with GerdQ <8 (p=0.038). ^*p<0.05. T lymphocytes, infiltration of intraepithelial T lymphocytes.
