2. Fig. 1
Significant (p<0.05) correlations (Spearman's) between (a) FEV1 and (b) FVC versus serum vitamin A concentrations compared to the absence of correlation between (c) FEV1 and (d) FVC versus serum vitamin D concentrations in patients with CF. A similar contrast in relationships with serum vitamin A compared to serum vitamin D concentrations is observed for PEF.
