  1. F values and statistics indicate main effect of deletion status for the models reported in the “Analysis 1: sensorimotor control in 22q11.2DS and sibling controls” section of this paper
  2. padj indicates p value after Bonferroni-Holm adjustment
  3. Effect size thresholds: ηp2 > .01 small, > .09 medium, > .25 large [25]
