The values of the interassay and intraclass correlation coefficients were high with rivaroxaban for the three chromogenic assays support the validity of this determination from serum samples despite minor systematic differences between the three tests.
Reliable values for method validity of organochlorine pesticides determination were investigated, in water by solid phase extraction and in sediment by Soxhlet extraction, followed by gas chromatography equipped with an electron capture detector.
However, we used several methods to increase the validity of our outcome determination and to reduce the possibility of confounding and reverse causality.
As set forth in Boardman, the county canvassing boards are vested with the responsibility to make judgments on the validity of ballots, and its determinations will be overturned only for compelling reasons when there are clear, substantial departures from essential requirements of law.

Therefore, the validity of GNSS supporting orbit determination for sampling and returning from lunar explorations is verified.
In order to check the validity of the developed hardness determination procedure, various materials and coatings were tested through nanoindentations and their Vickers HV and indentation hardness HIT were computed and experimentally verified versus the indentation depth, by means of SEM-supported observations of the occurring impressions.
Nonetheless, the validity of cause-of-death determination is questionable and has been found to differ across cancer types, time periods and ages at death [ 27].
In many instances the validity of the sample size determination and by extension the scientific validity of the study—one of the main aspects of the ethical review process could not be judged.
In order to enable cross-country comparisons, significant efforts have been made in standardizing the protocols for VA data collection and in enhancing the validity of cause of death determination (12– 12).
