From: Variations in the estimated intake of acrylamide from food in the Japanese population

  1. DR dietary record, FFQ food frequency questionnaire for validation analysis, SD standard deviation
  2. a Percentage differences (%) were calculated from the following formula: (“mean FFQ” − “mean DR”)/ “mean DR” × 100
