Fig. 1. Correlation between epidermal hydration and SCORAD score in the gromwell group. A significant positive correlation was observed (r=0.506, p=0.046 by Pearson correlation test). % Increase of epidermal hydration was calculated as {(the level of SC hydration at 10 weeks the level of SC hydration at 0 weeks)/ the level of SC hydration at 0 weeks}×100.
