The aim of the present study was to investigate trends in the incidence of primary THA and TKA in a well defined sample of patients with RA.
Our purpose was to investigate secular trends in the incidence of primary total hip and knee arthroplasties in a well defined sample of patients with RA.
In the current study, we applied VBM methods to a well defined sample of patients with autistic disorder with the goal of replicating prior whole brain findings in the literature reported for both gray and white matter.
Identifying the determinants of health-related quality of life (HRQOL) in patients with systolic heart failure (CHF) is rare in primary care; studies often lack a defined sample, a comprehensive set of variables and clear HRQOL outcomes.
Here, we used a temporally and spatially well defined sample of the meningococcal population and provide MLST data for all strains analyzed to allow for a thorough comparison with the mCGH results.
In conclusion in one experimental setup abundance profiles of metabolites and of selected low molecular weight proteins (dialysate analysis) and a comprehensive proteome profile after accumulation during a defined sampling time (analysis of the adsorbate) can be obtained from the same defects.
(2) Sampling frequency: The discrete Fourier transform (DFT) has a very well defined sampling of the frequencies, in order to be both complete and orthonormal.
Lack of a priori defined sample size calculations leading to insufficient sample sizes and ultimately insufficient statistical power [73]; studies with an insufficient sample size can thus lose their ethical justification [74].
We assessed whether or not each paper reported the following components: a clearly defined research question, rationale for the study design, a well defined sampling strategy and clear description of data collection.
