However, comparisons failed to reach statistical significance for congruent and incongruent multisensory stimuli presented in close temporal proximity: that is, for audiovisual stimuli where the SOA was smaller than 100 ms, AB’s error rates did not differ significantly from controls (for all p > 0.05).

The sentences
Multisensory gains with auditory stimuli leading by 300 ms approached significance (i.e., failing to reach significance with a Bonferroni correction), and significant RT costs were observed when the visual signal led by 200 and 300 ms for both congruent and incongruent multisensory stimuli (see Table 1 for the outcomes of the t test).
This difference in enhancement between our patient with PCA and the control group failed to reach significance with a Bonferroni correction, though with a p value of 0.03 it is importance to acknowledge the possibility of a Type II error.
