Fig. 2From: The evaluation of three treatments for plantar callus: a three-armed randomised, comparative trial using biophysical outcome measuresMedian change in hydration, elasticity, and texture for plantar callus at D7, D14 and D21 for potassium hydroxide (KOH), trichloroacetic acid (TCA) and podiatry treatment groups. Change in a negative direction of hydration and elasticity data represents a decrease in hydration and elasticity respectively. Change in a negative direction of texture data represents an improvement in texture. *represents a significant difference (p ≤0.01) compared to baseline (the podiatry group baseline values were those taken post podiatry treatment on D0)Back to article page
