Second step of standardization for sampling conditions: Using the estimated parameters of the measurement models, we predicted the concentrations that would have been observed assuming that all samples had been collected under the same standard conditions.
This 2-step standardization method is detailed in the Additional file 2 statistical appendix and outlined below: First step of standardization: Influence of sampling conditions on biomarker concentrations: The first step consists in a description of the association between sampling conditions and the level of each biomarker, adjusted for potential confounders.
Identifying the CDEs as the first step of data standardization not only facilitates collection of data and improves data quality, but also provides the foundation for data sharing and comparisons between studies.
The standardization of the assessment of medical students prior to their entry into medical practice, whether they join residency or not, is needed to complete the first and last step of the standardization process already in practice.
Then, the construction of the ESI is mainly composed by three steps: (i) standardization of each observation for all categories, (ii) computation of weighted average across the fifteen categories, and (iii) standardization of weighted average which is rescaled multiplying by 10 and adding 100 so that the ESI can have an expected value of 100 and a standard deviation of 10.
The authors propose developing a simple patient case reporting form for injury data reporting in the early phases of earthquakes as a first step to standardization.
As a result, our findings should be considered a 'first step' in the process of standardization.
As a result, our findings should be considered a 'first step' in the process of standardization of the definition of AKI in patients with cirrhosis.
Additionally, the volumetric pulsatility index (vPI) assessing the volumetric vascular impedance with spatiotemporal image correlation (STIC) and VOCAL could overcome these deficiencies, representing an important step in the process of standardization [ 43].
In the standardization steps of IHC analyses, two different antigen retrieval (AR) solutions, which are widely used for antigen retrieval in IHC studies [ 26], were evaluated - citrate buffer (10 mM sodium citrate, 0.05 % Tween 20, pH 6.0) and Tris-EDTA buffer (10 mM Tris-Base, 1 mM EDTA solution, pH ~9), at high (autoclave at 100°C, 10 min) and low (water bath at 65°C, 1 h) temperatures.
