  2. References (OR = 1) respectively: a male, b rural, c Cantho province, d SES middle
  3. Meaning of OR for example for the Mratio for the molar region: every year older gives a 2.5% higher chance for missing all non-sound molar teeth. The chance for females compared to males on this event is 31% lower, whereas subject with low SES are estimated to have a 28% higher chance compared to middle SES. Other independent variables showed no statistical significant effects.
