From: Effect of oral functional training on immunological abilities of older people: a case control study
Box-whisker plots of stimulated salivary secretion rate, concentration of IgA and its secretion rate. The horizontal bars indicate 10, 25, 50, 75 and 90% of the data, and data <10% and >90% are depicted in the plots. The data at baseline and at 3 and 6 weeks after oral functional exercise are labelled Baseline, W3 and W6. Saliva flow rate (a), IgA concentration (b), and IgA flow rate (c). Wilcoxon matched-pairs signed rank test (two-tailed) was used. *P < 0.05
