The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
NATA accreditation formally recognises facilities that meet the competency requirements to produce reliable technical results for a particular test method. [7] Service providers are accredited to perform particular tests within their accreditation scope, and are permitted to endorse their test reports with NATA's logo when providing accredited ...
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. [1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature), then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
In this example, the first row lists the trait being assessed (i.e., depression or anxiety) as well as the method of assessing this trait (i.e., self-reported questionnaire versus an interview). The term heteromethod indicates this cell reports the correlation between two separate methods.
Clinical peer review should be distinguished from the peer review that medical journals use to evaluate the merits of a scientific manuscript, from the peer review process used to evaluate health care research grant applications, and, also, from the process by which clinical teaching might be evaluated.
Certification is a comprehensive evaluation of a process, system, product, event, or skill, typically measured against some existing norm or standard.Industry and/or trade associations will often create certification programs to test and evaluate the skills of those performing services within the interest area of that association.
Lot quality assurance sampling (LQAS) is a random sampling methodology, originally developed in the 1920s [1] as a method of quality control in industrial production. Compared to similar sampling techniques like stratified and cluster sampling, LQAS provides less information but often requires substantially smaller sample sizes.
