Salivary protease inhibitory proteins (antileukoproteinase [SLPI] and cystatin [Cys]) concentrations of the control group (open column) and the oral dryness group (gray column). Values are shown in box and whisker plots representing the median, interquartile, and range. Cross mark and circle represent the means and outliers, respectively. emPAI, exponentially modified protein abundance index. Mann–Whitney U test, vs control; *p < 0.05
