The hierarchy of evidence is a rating system commonly used to evaluate the strength of evidence presented in medical research. The levels of evidence are a vital component of evidence-based surgical practice and are a valuable tool by which surgeons are able to understand and rank the surgical ...

In the same sense that NP-completeness of the q(n)-Step Non-deterministic Turing Machine Acceptance, where q(n) is a polynomial in the size of the input, provides us with very strong evidence that no NP-complete problem is likely to be solvable in polynomial time, using Short Non-Determi...
The tenets of evidence-based medicine include an emphasis on hierarchies of research design (i.e., study architecture). Often, a single randomized, controlled trial is considered to provide "truth," whereas results from any observational study are viewed with suspicion. This paper describes informat...

Randomized, Controlled Trials, Observational Studies, and the Hierarchy of Research Designs. Background: In the hierarchy of research designs, the results of randomized, controlled trials are considered to be evidence of the highest grade, whereas ......
New research explains why so many biological networks, including the human brain (a network of neurons), exhibit a hierarchical structure, and will improve attempts to create artificial intelligence. The study, published in PLOS Computational Biology, de
BACKGROUND: In the hierarchy of research designs, the results of randomized, controlled trials are considered to be evidence of the highest grade, whereas observational studies are viewed as having less validity because they reportedly overestimate treatment effects. We used published meta-analyses to ...
Plethora or paucity: A systematic search and bibliometric study of the application and design of qualitative methods in nursing research 2008–2010 One of the problems with qualitative methodology for nursing research is its place in the hierarchy of evidence (HOE); another is its comparison to the...
The uncritical acceptance of Maslow's need hierarchy theory despite the lack of empirical evidence is discussed and the need for a review of recent empirical evidence is emphasized. A review of ten factor-analytic and three ranking studies testing Maslow's theory showed only partial support fo...
