To minimise measurement variability, a central laboratory was identified for measuring HbA1c and lipids in the OPTIMISE trial.
In each case, three identical samples were measured and their standard deviations calculated in order to determine the measurement variability.
For almost all analytes, measurement variability was the smallest component of the total variation.
Measurement variability was low for all analytes, ranging from 2.4% (total TSNAs, NAT) to 9.5% (geraniol).
We found that measurement variability does not increase with scale for all fuel components.
Investigators' prior belief, compromised blinding, and scope for measurement variability are a fatally synergistic combination.
Traditional methods for the evaluation of in vivo spine kinematics introduce significant measurement variability.
Measurement variability does not exceed magnitudes of altered scapular muscle activities as reported in previous studies.
Investigative noise is of two general kinds: random biological (and measurement) variability, and bias.
To assess inter-device measurement variability with the Stratus optical coherence tomography (OCT).
Models were then validated by comparison with air and mass temperature data: all predicted 84 93% of measurement variability.
