Summary table of post hoc clinical regressor effect of occipital–parietal k₃ analysis

Regressor	Baseline	Follow-up	β visit	β clinical	β visit*clinical
DKEFS Stroop III	122.20 ± 29.92	140.69 ± 39.79	−0.70	−0.12	0.39
DKEFS Stroop IV	137.28 ± 29.77	159.33 ± 45.59	−0.59	−0.38	0.49
RBD	11/16		−0.69	−0.89

β coefficients are presented for selected AIC minimizing model. If the independent effect model was selected, β coefficients for independent effect of visit (β_visit) and clinical regressor (β_clinical) are presented. If the interaction model was selected, β coefficients for the marginal effect of visit (β_visit), marginal effect of clinical regressor (β_clinical) and visit by clinical regressor interaction term (β_{visit*clinical}) are presented. Statistically significant model effects (P < 0.05) are bolded. Descriptive statistics for the clinical regressors are presented for baseline and follow-up visit as mean ± SD for Stroop measures and as ratio of participants for RBD. DKEFS = Delis–Kaplan Executive Function System; RBD = rapid eye movement sleep behaviour disorder.
