aOR, Adjusted odds ratio; BMI, Body mass index; DM, Diabetes mellitus; CPI, Community periodontal index; LA, Loss of attachment.
AR (Attributable Proportion) = (Odds Ratio−1)/(Odds Ratio).
PAR (Population Attributable Proportion) = ((Exposure %) × (Odds Ratio−1))/(1 + (Exposure %) × (Odds Ratio−1)).
