Standardised coefficients (beta) and p-values, one regression model for each fatigue measure. The difference of each fatigue measure is the dependent variable. N = 103 for focus score data among the 122 follow-up patients, other variables had larger samples. The P-values for each model were 0.88, 0.66, 0.96 and 0.82, respectively. ANA, antinuclear antibodies; UWS, unstimulated whole saliva. FSS, VAS, FACIT-F, vitality, see Table 1 legend.
