  1. Correlation coefficient r and bias: results are provided as compared with actual height; measures are provided as mean ± SD
  2. Actual height: height measured in the erect position using a vertical calliper; provided height: height provided by the healthy volunteers; measured height: height measured in the supine position, using a soft tape metric ribbon
  3. Index: two different formulas were used (I 1, 2); hand: five formulas were used, three based on length (HL 1–3) and two combining width and length (HW 1, 2); ulna: three formulas were tested (U 1–3); tibia: five formulas were tested (T 1–5); reference Chumlea was measured with the patient positioned recumbent, knee raised vertically with a 90° angle between femur and tibia, and the calliper positioned under heel and over femoral condyle of the leg; simplified Chumlea was measured with the patient laying supine and the calliper positioned under heel and over patella’s upper line (see Fig. 1). All formulas are provided within the Additional file 1: Online Repository
  4. Italic value indicates the reference value for height, that was measured in the erect position
