  1. Values are mean ± SD.
  2. *The mean sAA value in the original report (Goi et al., 2007) was 17.41 ± 13.50 (± SD, × 104 U/ml), however this value was probably an incorrect calculation. In this table, we multiplied the original value by 10-3.
  3. ** Our measurement is similar to that recommended by the manufacturers.
  4. sAA: salivary alpha amylase, sCgA: salivary chromogranin A, sIgA: salivary immunoglobulin A, EKM: enzyme kinetic method, DCS: dry chemistry system, EIA: enzyme immunoassay, ELISA: enzyme-linked immunosorbent assay.
