Using serial tape-strips and swabs from healthy controls and AD patients, inter-individual variation within the bacterial skin community was analysed using PERMANOVA, while differences in ASV richness was analysed using generalised linear modelling and likelihood ratio testing (chi-squared). Differences in community composition and ASV richness associated with skin depth and skin group (a combination of body location and AD status) were performed using PERMANOVA and mixed linear modelling while accounting for inter-individual variation
