- Correlations between the overnight changes (before and after PSG) in plasma VEGF and bFGF concentrations (ΔVEGF and ΔbFGF, respectively) and hypoxia-associated parameters of OSAS severity were analyzed by using the Pearson’s correlation coefficient. Coefficients of correlation are represented by rs and statistical probabilities by P values in parentheses.
