Colorimetric assessment of skin blanching. (a) Box plots of baseline‐adjusted, untreated control site‐corrected values of skin colour change measured by the colorimetric parameter a* (Δa*) area under the curve (AUC_0–32). The horizontal line represents the median and the diamond represents the mean, with the box representing the IQR and the whiskers showing the range within 1.5 × IQR. (b) Mean Δa* skin blanching score obtained from two successive measurements at each time point. ^†Lower score indicates greater degree of skin blanching. BD, betamethasone 0.5 mg/g (as dipropionate); Cal, calcipotriol 50 μg/g; CP, clobetasol propionate 0.5 mg/g cream; FA, fluocinolone acetonide 0.25 mg/g ointment; IQR, interquartile range.
