Several patient characteristics for the six groups are shown; age, distribution of women and men in each group, the total number of medications used, the total XI-scores, salivary flow rates (in mL/min), and the salivary pH of UWS, CH-SWS, and A-SWS. The age is presented as mean with standard deviation (SD). For the number of medications used, the total XI-scores, salivary flow rates, and salivary pH, the median with corresponding interquartile range (IQR) is shown. The distribution of women and men is given in percentages
