†P1; P-value of within CF group differences between Test 2 and Test 1 (ΔT2-T1); compared using a paired t-test
‡P2; P-value of within placebo group differences between Test 2 and Test 1 (ΔT2-T1); compared using a paired t-test
§P3; P-value of the difference between pre- and post-treatment between the CF and placebo group using a mixed ANOVA.
