The maximum head breadth was measured as the maximum diameter between the two euryons using spreading calipers (electronic width sensitivity of 0.1 mm).
SD--Standard Deviation, calculated for maximum head length (MHL), maximum head breadth (MHB) and Cephalic Index (CI).
For example, to reduce the risk of head entrapment, openings in the bed system should be small enough to prevent passage of the widest part of the head (i.e., head breadth measured across the face from ear to ear).
* Body part entrapped and, if possible, the part's size (e.g., head breadth, neck diameter, chest depth)
These included thigh length, leg length, upper arm length, forearm length, bi-iliocristal diameter, bitrochanteric diameter, transverse chest diameter, chest depth, biacromial diameter, head length, head breadth, chest circumference, upper arm circumference, calf circumference, biocular breadth, bizygomatic breadth, bigonial breadth, upper face height, trunk length, and crown-rump length.
