P values were obtained by using Tukey's adjustment for multiple comparisons. Mean values were obtained by using weighted least-squares regression. *, significant (P ≤ 0.01) differences between all means; †, significant (P ≤ 0.01) difference between means (PcP− versus PcP+); ‡, significant (P ≤ 0.01) differences between means (BD versus PcP−, BD versus PcP).
