Kappa unadjusted kappa, 95% CI 95% confidence interval, PABAK prevalence-adjusted bias-adjusted kappa, PI prevalence index, BI bias index, IBD inflammatory bowel disease. Reliability for medical, allergy and food intolerances was determined using a kappa statistic or PABAK. Celiac disease, irritable bowel syndrome (IBS), heart burn/reflux, hiatus hernia, intestinal parasites, and no medical diagnosis had 100% agreement. IBD, who diagnosed your medical condition, who diagnosed your food allergy, allergy test, and blood allergy test all had substantial agreement. Allergies to tree nuts, sesame, soy, sulfites, egg whites, peanuts, fish/seafood, wheat, mustard, eggs, and monosodium glutamate (MSG) had 100% agreement. Intolerance to soy milk, meat, almond milk, poultry, coconut milk, juice, and fruit had 100% agreement
