Reference values for lung function: past, present and future.
Studies on spirometric
reference values for the elderly have been reported since 1996,[15],[16],[17],[18],[19] and most of them were for Americans or Europeans.
On the other hand, Nomograms of the Spirometry GLI
reference values with mean calculated values has been made to ease the clinical practice as mentioned in Fig.1.
Reference values for MCV are 80 to 100 femtoliters or cubic micrometers.
The counting of the number of utterances produced by each child did not follow all the rules established in the study to obtain the
reference values of MLU-w, i.e., 100 utterances per child.
In another analysis with an adjustment for the age difference in the two groups,
reference values were calculated to compare the patients with the control population [14].
Observed were deviations of measured characteristics from
reference values obtained on coordinate tactile measurement machine.
Single fiber EMG
reference values: reformatted in tabular form.
(f) the phase angle
reference values: valid under V/F mode; this generally is not for the external input, instead of the internal automatic continuous calculation.
To follow this decision process,
reference values are required6.
Article 7 states that
reference values must be determined for GHG emissions for the entire life cycle of fossil fuels used for transport (extraction, refining, transport and combustion).
