Table 1. Demographic data of patients with cystic fibrosis and vitamin E deficiency and those with normal levels.
Data are presented as number (%), mean ± standard deviation, or median (interquartile range).
aFisher’s exact test; bMann-Whitney U test; cStudent t-test; dPearson's chi-square
P-value < 0.05 is considered statistically significant.
Bold values indicate statistical significance.
IQR: interquartile range; SD: standard deviation; BMI: body mass index; ADEK: fat-soluble vitamins A, D, E, and K
