Table 4. Laboratory results 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).
aStudent t-test; bMann-Whitney U test
P-value < 0.05 is considered statistically significant.
Bold values indicate statistical significance
