  1. aLogistic regression models did not converge when unit was included; adjusted for home only
  2. bOdds ratios calculated for: energy intake, per 100 kcal increase; protein intake, per 10g increase; energy/body weight, per 10 kcal/kg increase; protein/body weight, per 0.1 g/kg increase; adequacy ratio (MAR/NAR) scores are per 0.1 unit increase: < 1 being lower odds of the outcome, 1 = no association, and > 1 meaning higher odds of the outcome
  3. cOdds ratios adjusted for resident level characteristics that were prevalent and known to be associated with malnutrition (MTD, ONS, requiring physical assistance)
  4. dNiacin equivalent
  5. eInternational unit
  6. * P < 0.05
