Table 1. Visual analogue scale distribution at baseline and follow-up (averaged over 7 days).

VAS scores (raw data)	Mean (SD)	Median	Interquartile range	Range*	Kurtosis	Skewness
Baseline	59.1 (14.9)	59.4	48.0 to 68.9	27.3 to 96.6	−0.382	0.133
Follow-up	45.6 (24.4)	42.7	26.8 to 67.0	0 to 98.4	−0.870	0.202

* The minimum baseline score is a little lower than 30 mm at screening, which took place a week before the commencement of the study.
