Mean (95% CI) serum vitamin A (μmol/l) in control subjects and subjects with CF. Serum vitamin A was not significantly different between control and CF children (1.45, 1.25–1.64, n=25 vs. 1.11, 0.95–1.27, n=39, p=0.08) but higher in control adolescents (1.73, 1.61–1.85, n=65 vs. 1.19, 1.05–1.34, n=45, p<0.0001) and adults (2.08, 1.94–2.22, n=48 vs. 1.50, 1.37–1.63, n=54, p<0.0001) compared with the CF group.
