Multiple comparisons of quality of life for patients with normal cognition.

Fixed effects (type III) P-value Significance Variation (percentage) F (DFn, DFd)
Time x receiving CBD or placebo 0.0139 * 4.777 F(2, 40) = 4.763
Timepoint 0.0204 * 4.530 F(1.820, 36.40) = 4.517
CBD or placebo 0.4301 Ns 2.241 F(1, 20) = 0.6486
Patients < 0.0001 **** 69.10 F(20, 40) = 6.889
