Results obtained using an ANOVA on post-product use results with fixed effects of product, period, sequence and a random effect of subject nested within sequence (*indicates p =  < 0.05). Participants with assessments flagged to indicate non-compliance, who also meet the performance outlier threshold (± 1.5 × IQR), have been excluded from the analysis of this data

ANOVA, analysis of variance; IQR, interquartile range

Baseline defined as − 85 to − 45 min pre-product use
