Comparison of zonulin concentrations according to BMI levels.

BMI Levels	Group 1	Group 2	Group 3	Group 4	p Value
<25	12.24 (1.77–99.12)	10.50 (6.00–15)	No data	4.9 (10.12–23.88)	0.601
25–29	11.13 (2.33–149.12)	18.5 (2.33–101.20)	108.12 (66.12–150,12)	6.7 (0.16–150.12)	0.015

The levels of categories are presented as the median (min–max) for numerical variables and as the number of observations and percentile for nominal variables. The Kruskal–Wallis test was applied. Values in bold represent statistically significant outcomes. Abbreviations: BMI: body mass index.
