  1. This table shows the weight status comparison by using WHO’s 2007 BMI-for-age tables vs. the study simplified overweight screening instrument
  2. Overall percent agreement = 100% x (a + d)/(a + b + c + d) = 100% x 150/168 = 89%
  3. Positive percent agreement = 100% x a/(a + c) = 100% x 59/59 = 100%
  4. Negative percent agreement = 100% x d/(b + d) = 100% x 91/109 = 83%
