As one of the tools for this type of optimization, genetic algorithm has a high quality and validity.
All these quality indicators are regarded when results of a study are reported and the data is made publicly available, and are meant to ensure a high quality and validity of the survey results.
The trials were of high quality and validity, scoring the maximum for both.
The Danish national registers have high quality and validity [ 26] and such analysis is only possible in Scandinavian countries.
All trials were of high quality and validity, scoring 5/5 on the Oxford Quality Scale and 16/16 on the Oxford Pain Validity Scale.
In total, these three analyses involve 81,664 patients enrolled in randomized controlled trials of high quality and validity in the settings of OA, RA, back pain, and ankylosing spondylitis.
Research required to be submitted to regulatory agencies in member countries of the Organisation for Economic Cooperation and Development OECDD) must also follow OECD GLP principles (OECD 2005), which serve to substantiate the high quality and validity used for determining the safety of chemicals and chemical products in those countries.
The data stored in these registries have demonstrated both high quality and validity [ 28], affirming that the registries are a valuable resource for studying maternal and obstetric health outcomes as the identification of preeclampsia is shown to be accurate in such databases [ 29].
Sensitivity analysis showed that choosing only studies of higher quality, higher validity, those that reported intention to treat results, or were larger made no appreciable difference to the overall conclusion.
Using only studies with higher quality and validity scores, or studies with higher rather than lower preference outcomes made no difference (preferred outcomes were patient rated global or pain, lower preference undefined improvement and physician rated global outcomes).
