MeanDecreaseGini index of 35 operational taxonomic units (OTUs) and severity scores. Gini index of OTUs using Random Forest to analyse associations between the 35 abundant OTUs and severity scores. The larger value of MeanDecreaseGini, the greater the importance of the OTUs for balanoposthitis (BP) or healthy controls (HC). Taxonomic levels are represented with prefix f_: family, g_: genus, s_: species.
