Table 2. Generalized estimating equation (GEE) analysis.

Parameter Estimate Z-value p-value
Intercept −4.7675 −3.24 0.001
Number of stimuli 0.2333 2.13 0.033
Resting motor threshold 0.0715 2.35 0.019
Resting motor threshold× Number of stimuli −0.0019 −0.71 0.481

Estimates and p-values are shown for the number of consecutive stimuli, arousal, fatigue, resting motor threshold and the interaction between arousal and fatigue. P-values in bold highlight a significant effect.
