Comparing components of the nutritional intake between controls (C) and periodontitis patients (P) using Wilcoxon test (uncorrected p-values are shown), p-values in bold are nominally significant and p-values marked with an asterisk (*) are robust under multiple testing according to Bonferroni method.
