Only FEV1 as a percentage of a normal value predicted from age, gender and height was used for statistical analysis.
Recently, Craig and colleagues [ 21] argued that there is a lack of consensus as to what constituted a normal value.
A normal value is defined as a relative probe signal between 0.7 and 1.3.
A platelet count (PLTC) that is elevated above a normal value is defined as thrombocytosis.
Critically ill patients may present high SIG with a normal value of SBE as a result of associated hypochloremic alkalosis.
The injected human cells seemed to behave as retinal cells should, and the treated rats retained some six layers of rods and cones in their retinas, as much as half the normal value.
Lymphopenia is defined as a decrease below normal value (often 1.5 × 103 cells/µL) of the blood circulating lymphocyte count; it reflects an impairment of the adaptive immune system.
These values were removed from the study population, and the resulting adjusted male median was used as the normal value.
For the purposes of this study the normal range was taken as being the normal value ± 30%.
Reference values were obtained from apparently healthy volunteers: 0.105 μg/L was determined as the upper normal value (Roche Diagnostics).
