The calculation was based on the normal range of rotation (mean 170° with a standard deviation of 30°) in the forearm.
Subjects had to be in good health and have a serum IGF1 level within the normal range of −2.0 to +2.0 SDS (age-adjusted standard deviation scores).
Since this study defines the normal range of the TFA in boys and girls and also the standard deviation, it helps divide normal physiological variations from pathologic ones.
The normal range of OPC number was defined as the mean ± one standard deviation of OPC counts from 35 fields of view of white matter from blocks from five different normal controls.
Normal range of motion should be preserved.
Below and above the normal range, deviations of the thermo-dependence of growth from the Arrhenius law reveals the inability of cells to maximize their growth rate [ 15], but little is known about the reasons why microbes are unable to maximize their growth rate at divergent temperatures.
The maximum normal ranges of 2 and 3 standard deviations (SD) are distributed between 0.82 and 1.18 (Mean ± 2SD, 95% CI, P = 0.05), and between 0.73 and 1.27 (Mean ± 3SD, 99% CI, P = 0.01), respectively.
In all limbs, each of these variables that were initially outside the normal range (±1 standard deviation) showed improvement.
A cut-off point of greater than 1.0 exceeds the normal range by about 2.5 standard deviations.
Subjects were also excluded if their reported clinical parameters exceeded the standard deviations of the normal range.
