Relationship between food items based on food frequency questionnaire (FFQ) and the onset of autoimmune diseases (DM, AIT, JIA, and IBD)^a. ^a Autoimmune diseases in this study are: AIT, autoimmune thyroiditis; DM, type 1 diabetes mellitus; IBD, inflammatory bowel diseases; JIA, juvenile idiopathic arthritis; PCI, plant consumption index; STI, sweet treat index. Case group = 105 adolescents who later developed autoimmune diseases^a. Four children with matching age, sex, and residential areas were chosen for each child in the case group, generating the control group of 420 children. Data were collected approximately 2 years prior to diagnosis. Median age at the time of the diagnosis was 13.8 (IQR 12.3–15.5). Each child in the control group were compared with four matching children in the control group using conditional logistic regression (survival cox regression): adjusted OR considered each of the 16 food items and central obesity. p > 0.05 for all food items
