Baseline scale scores of the BAI and IDS were added to control for baseline symptom severity.
To assess correlates of the disorder, we compared the apraxia and Control groups for baseline scaled cortical thickness at each ROI using independent samples t-tests.
The full model ANCOVA allowed for testing of first and second order interactions between the covariate (baseline scale scores) and both factors.
This study also demonstrated a significant effect of the intervention despite higher baseline scores in this sample (mean baseline scaled score 85.3, compared to 77.2 in the previous study).
The Multidimensional Pain Inventory score patterns of this study were depicted as graphs of the mean Multidimensional Pain Inventory baseline scale scores and compared to the patterns described by Turk and colleagues and our previous studies on this topic using the rank orders of the three subgroups within one Multidimensional Pain Inventory subscale [ 22, 23].
Upon arrival and consenting, participants completed the baseline descriptive scales (visit #1 only), the mechanical pain test, and the SOWS and PANAS.
At baseline, all scales and single items seemed to distinguish between subgroups of patients on the basis of Karnofsky Performance Status.
We estimated odds ratios (OR) and 95%-confidence intervals (95%-CI), adjusting for headache days at baseline (interval scaled), education, age (interval scaled), gender and BMI classes (normal, overweight, obese).
On average, subjects had good visual function at baseline (Monoyer scale, 8.50 ± 1.99; Parinaud scale, 2.30 ± 1.18) and experienced little change by week 12 (change in Monoyer scale, 0.03 ± 0.80; change in Parinaud scale, -0.05 ± 0.71).
