  1. ab Primary PLS models M1 to M4. VIP values > 1.0 marks influential variables (see Methods). Consistent positive (+) or negative (-) association for the regression coefficients for each y variable; otherwise blank.
  2. b Variable units and units of measures used for derived variables.
  3. c Some of the previous caries x variables (n = 18) derived from the y1-y18 baseline caries variables (see Methods).
  4. d The plaque variables except for phosphate and plaque % of lbc+/ms+, lbc+/ms- or lbc-/ms+ (see Methods).
  5. e Some of the 45 diet variables (see Methods).
  6. f The whole saliva variables except for chewing rate. The parotid saliva variables except for the same factors in resting parotid saliva and derived secretion rates for some components in both salivas (see Methods).
