Figure 3 Volume percentages of glands (VPGL; A), stroma (VPS; B), infiltrate (VPI; C), and intestinal metaplasia (VPIM; D) for different degrees of corpus atrophy according to the updated Sydney system in 124 gastric corpus biopsies. In the moderate atrophy group only one case showed intestinal metasplasia (VPIM, 3.1%; mean VPIM, < 0.1). The Student's t test was used to calculate p values. Grade of atrophy: group 0, no atrophy; group 1, mild atrophy; group 2, moderate atrophy; group 3, pronounced atrophy.
