Intraepithelial micronutrient levels before and after obesity therapy using a low-calorie formula diet (n = 32) and during further follow-up (n = 9). Samples with no detectable micronutrient levels were excluded in this analysis. Data are presented as median +/− quartiles (boxes) and 1.5 interquartile ranges (whiskers). The dotted lines indicate the reference ranges. Statistical analysis: paired t-test.
