Data shown represent Days 2, 3 and 4, where sample size was N = 228, N = 226 and N = 224, respectively. Day 3 Pearson correlations (95% confidence intervals) against the WURSS-21 were 0.925 (0.903, 0.942) for the WURSS-44, 0.849 (0.808, 0.882) for Jackson, -0.793 (-0.739, -0.837) for SF-8 physical, and -0.547 (-0.448, -0.632) for SF-8 mental. Correlations to the WURSS-44 were 0.879 (0.846, 0.906) for Jackson, -0.799 (-0.746, -0.842) for SF-8 physical, and -0.599 (-0.507, -0.677) for SF-8 mental. Jackson correlated to SF-8 physical at -0.748 (-0.684, -0.800) and to SF-8 mental at -0.555 (-0.457, -0.640). All associations were statistically significant at p < 0.001.
