It involves several steps, including initial sampling, regression and adaptive sampling.
A total of 858 samples passed all filtering steps including 487 samples with 10-year follow-up data (213 relapse; 274 no relapse).
The final color of the image presented to the viewing pathologist depends on several steps through the imaging pathway, including sample illumination, magnification, image capture, compression, storage, and reproduction on the computer display as shown in Figure 1.

The primary inclusion and exclusion criteria were chosen to meet the objective of the study: to examine how many individuals are included in PRO validation studies, and how developers of PRO measures report the steps involved in psychometric validation, including sample size determination.
For these reasons, the use of adequate blanks is essential for every step of the biomonitoring process, including sample collection and every point in the chemical analysis.
One is the difficulty of realizing real-time monitoring, and the other is that a blood test needs too many steps, including blood sampling and chemical analysis [3].
All processing steps, including biomass collection, sample preservation, nucleic acids extractions and sequencing library preparation, are critical and require specific protocols and robust methods in order to ensure comparability of results and limit potential biases30,31,32.
Also, it is worth noting that the process of biomarker discovery involves many critical steps including study design, sample preparation, protein and peptide separation and identification, and bioinformatics and data integration issues that must be carefully controlled before achieving independent confirmation and validation.
The multiple steps included in sample preparation (RNA to cDNA preparation, data acquisition, normalization of data) are all possible steps for introduction of variations.
