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.
