The table displays the results for the final model that was based on the data collapsed across the significant sensors, showing the main effect of SOJ, when the model was fitted on a per-sensor basis. The table depicts the anterior cluster.

The asterisk signifies the factors that were significant after false discovery rate correction, applied after the same model was fitted for every sensor separately.
