IQR: interquartile range.
VAS: Visual Analog Scale.
RMDQ: Roland-Morris Disability Scale.
SF36: Short Form (36) Health Survey.
GSC: Global Satisfaction with Care.
¹Wilcoxon rank sum 2-sided; ²higher scores on SF36 subscales and composite scores indicate more positive health; ³higher scores on GSC indicate greater satisfaction with care; ⁴ < 0.01; ⁵ < 0.001.
