Table 4. EGD Biopsy Practices in 1985, 1995 & 2005.

Table 4. The EGD biopsy practices among the subsample cohorts are described. As the practice of obtaining routine biopsies from the duodenum, stomach and esophagus has changed from 1985, 1995, and 2005, the proportion of subjects with any histologic abnormality from the duodenum, stomach and esophagus has declined.
