This study aims at assessing the reduction of consumption of corticosteroids (same mid-potent corticosteroids for all patients) afforded by the use of a specific emollient in comparison to the usual one in subjects suffering from atopic dermatitis.
The study is conducted in compliance, as closely as possible, with the current version of the world medical association declaration of Helsinki, local regulations based on International Council on Harmonisation (ICH) guidelines for Good Clinical Practice.
The primary objective of this study is to compare the tested emollient and the usual emollient through the weight of used dermocorticosteroid. The weight of used dermocorticosteroid is compared at the end of the study by a Student t-test (or a non parametric Wilcoxon test depending on the data distribution).
The following hypotheses are used for the estimation of the sample size calculation:
Statistical analyses is performed with SAS® version 9.4 or higher (SAS institute, North Carolina, USA).
Continuous variables are summarized as number of observations, mean, standard deviation, standard error, median, minimum and maximum (95% confidence interval will be provided if necessary). For categorical variables, subject counts and percentages will be provided.
Analyses use 2-sided tests at the 5% significance level, except the normality tested at the threshold of 1% (Shapiro-Wilk test).
