slightly significantp = 0.045
The mixed-model analysis of variance showed a significant effect of status (developing, not developing; p < 0.001) and no significant effect of time (baseline, follow-up; p = 0.38), while the interaction of status and time was shown to be slightly significant ( p = 0.045), thus suggesting that the change in MRPI values from baseline to follow-up evaluation was higher in patients with PSP-P developing VSGP than in those not developing VSGP.
