Is sex a proxy for mechanical variables during an upper limb repetitive movement task? An investigation of the effects of sex and of anthropometric load on muscle fatigue

Table 2 Results of the GEE analysis for sex and muscle RMS

	Sex	Muscle	Sex × muscle	AL
With AL covariate	χ²(1) = 4.17, p = 0.04*	χ²(1) = 8.48, p < 0.01**	χ²(1) = 2.03, p = 0.15	χ²(1) = 2.12, p = 0.15
Without AL covariate	χ²(1) = 2.54, p = 0.11	χ²(1) = 8.67, p < 0.01**	χ²(1) = 2.01, p = 0.16	NA

*A main effect with significance set at p < 0.05
**A main effect with significance set at p < 0.01
The values in the parenthesis are the Wald Chi-square value and the corrected p values for RMS values and 95% confidence interval for difference for the pairwise comparisons.
