(A) Baseline TEWL results from 3 body areas (volar forearm, supraclavicular neck, upper posterior torso over the scapula). n = 10 per group. (B) Difference between baseline TEWL and TEWL at food dose 2 or 3 during the OFC. n = 9 per group. (C–H) Baseline TEWL on volar forearm shown by age (n = 107), sex (n = 107), race (n = 106), ethnicity (n = 105), BMI (n = 107), and AD status (n = 107). (C and G) Simple linear regression results with baseline static TEWL as the dependent variable and (C) age or (G) BMI as the sole independent variables.
