From: Validation study of villous atrophy and small intestinal inflammation in Swedish biopsy registers

  1. *Only includes biopsies with villous atrophy. 46 individuals with their first "positive biopsy" (characterized by villous atrophy) after the age of 15 years had had a biopsy without VA when aged ≤ 15 years. Including them, the proportion of individuals with villous atrophy having "any small intestinal biopsy" ≤ 15 years of age was 36.9%.
  2. #Only includes biopsies with inflammation. 24 individuals with their first "positive biopsy" (characterized by inflammation without villous atrophy) after the age of 15 years had had a normal biopsy when aged ≤ 15 years. Including them, the proportion of individuals with inflammation having "any small intestinal biopsy" ≤ 15 years of age was 6.3%.
