Such large studies, investigators said, tend not to be repeated.
In many studies, investigators have perceived the number of repeated measurements as a fixed design characteristic.
Then, incorporating study arms of TIs in intervention studies, investigators may compare TIs with standardized interventions statistically and clinically.
In two of the best designed studies, investigators from the University of Oxford analyzed data from a Swedish registry of hospital admissions and criminal convictions.
When skin-mounted accelerometers are used in gait and other studies, investigators should consider performing test/re-test analyses to ensure that sensor data are not affected if sensor replacement is required by design or by accident.
In long-term (10- to 20-year) studies investigators have documented component survivorship of 95%-100% in both cemented and cementless applications, which compares most favorably to the best fixed-bearing knee replacements currently available.
"Today, we're continuing to discover that many illnesses may be linked to modifiable risk factors like diet". The key to establishing clear and accurate dietary advice may lie in the type of studies investigators conduct.
After demonstrating that the vaccine prevented cocaine from reaching the brain in earlier animal studies, investigators are now enrolling active cocaine addicts in a Phase I randomized control study to test how it works in people.
In the case of large cohort studies, investigators may like to have slides from each case sectioned prior to use, however this could lead to qualitative differences in staining between sections cut earlier or later.
"In several earlier studies, investigators usually exclude important elements of training, fatigue and some core human side of reliability as the maintenance workforce was evaluated (see Khalili-Damghani et al. (2013b).
However, in these studies, investigators administered amounts of contrast that exceed current practice, measured RBF with techniques of limited accuracy, and performed measurements only for a few hours after radiocontrast administration.
