Table 3.

Patients’ pain intensity depended on the following statistically significant variables from the analysis of variance (d.f. = 914) on morning and evening pain intensity values from day 1 to 5

Effect	P value	Interpretation
Treatment (ibuprofen‐foam versus comparator alone)	0·0003	Ibuprofen‐foam reduces painintensity
Time (between assessments)	<0·0001	Pain intensity for all patients decreases over time
Gender (women)	0·01	Women have less pain
Age	<0·0001	Older people have less pain
Baseline pain intensity	<0·0001	High baseline pain level, associated with high levels of pain at any time or with any treatment or other included variables
Baseline ulcer size	<0·0001	Larger ulcers, associated with higher pain levels
