Table 2.
Statistical parameters of intratester reliability of %BF assessments by 4 different anthropometric formulas (JP7, JP3, P3, and BIC), computed for three pairs of measurements (1–2, 1–3, and 2–3) performed by two testers.

aTEM, SEM, and MDC are expressed in the same units as the measured quantity (%BF).
bICC stands for ICC (2,1)—the 2-way random model, single score intraclass correlation coefficient; it is dimensionless, ranging from 0 to 1—the higher, the better [22].
