The main effect group showed that both groups also did not differ with respect to intrasubject variances (F 1,21) = 2.88; p = .104).104
There were no differences between groups in positive affect as measured by the PANAS prior and after the fMRI session (PANAS positive affect, main effect GROUP, Pre/Post fMRI and interaction n.s).. See Table 1 for mean values.
All main effect group comparisons in conventional bands had small effect sizes.
The results were analyzed by two-way analysis of variance (ANOVA) to show an influence of particles (main effect), group (main effect) or the combination of particles and group (interaction effect).
Concomitant non-opioid drug use versus no concomitant drug use had no effect on P300 amplitudes (main effect group: p = 0.69, group × electrode interaction p = 0.88).
A two-way ANOVA analysis (main effect: group and time; interaction: group and time) was applied to compare lesion fluorescent pixel numbers among groups.
The significance for the 2 main effects (group and hemisphere) and interaction (group × hemisphere) were examined.
For the two sets of comparisons, both main effects (group and day) and interaction (group versus day) were obtained as statistical parametric maps.
The full factorial model is reported in Table 2 and included all main effects (group and dose) and the group by dose interaction, and the main effects only model for serum ORAC together with degrees of freedom and p values.
The AD and MCI groups exhibited similar functional connectivity patterns compared with that of the NC group (main effect of group, F2,86 = 2.55, P = 0.084) and 2(c)).
