Table 2. Factors influencing salivary IgA secretion according to the saliva collection method.
Age | Gender | Sampling time point | Number of samples collected | |
(Young/Elderly) | (Male/Female) | (Morning/Afternoon) | (1, 2, 3 times) | |
p value | ||||
Swab method | 0.4293 | 0.1484 | 0.8403 | 0.0081 |
Aspiration Method | 0.4668 | 0.3628 | 0.0314 | 0.1069 |
p values were obtained using multi-factor ANOVA (factors: sampling method, age, gender, sampling time point and number of samples collected). Results show correlation of corresponding salivary IgA secretion rate between samples collected by the aspiration method and swab method.
