We have, however, compared data on comparable young age-matched controls measured at the two sites, and found no differences in any of the gait parameters, and therefore do not consider that the use of two different sites has introduced any systematic error.
Cases and matched controls were measured in singleton within the same batch.
Levels of sMER and sAXL in the plasma of 107 SLE patients and 45 matched controls were measured by ELISA.
In a sample of 278 patients and 70 matched controls, the measure differentiated between people with normal vision and people with low vision.
This matches controls for measured or unmeasured personal confounding characteristics that do not vary over the relatively short time, such as gender, age, and genetic factors [ 20].
Using three SLE patient cohorts and matched controls, microsatellite length was measured and association with the presence of disease and the occurrence of specific disease manifestations was assessed.
Cholesterol and oxidized cholesterol metabolite serum levels of FH and of healthy, gender/age matched control subjects were measured by combined gas chromatography – mass spectroscopy.
Fifty-nine motorcyclists with previous traffic offences, and 54 matched controls, were compared on measures of impulsivity, response inhibition, risk-taking behavior, and risky decision making.
Longer lengths of stay and higher mortality in cases compared with matched controls indicate that the measures are discriminatory and indicate the likely occurrence of a safety event.
The purpose of the current study was to characterize the gait profile of patients with knee OA compared to matched controls using a new measuring system that can be applied in clinic settings rather than laboratory settings.
HCV patients had consistently worse outcomes than matched controls across almost all outcome measures, though some measures of healthcare resource use did not reach significance.
