  1. aLogistic regression models did not converge when unit was included; adjusted for home
  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 lowers odds of the outcome, 1 = no association, and > 1 means higher odds of the outcome
  3. cProportion consumed relative to the Recommended Dietary Allowance for a given nutrient (NAR) or average of all nutrients (MAR), to a maximum of 1.0, which indicates the Recommended Dietary Allowance was met or exceeded
  4. dOdds ratio adjusted for home, age, sex
