Pearson correlation coefficient MUAC vs. BMI = 0.78; p < 0.0001

  1. Malnutrition was defined as BMI <18.5 kg/m2 and by mid upper arm circumference <22 cm in women and <23 cm in men
  2. SE standard error
  3. p < 0.0001, we could reject the null hypothesis that the two methods agree on malnutrition at random
