Evidence is a facet of Trust
The assertion support may be strong or weak.
The strongest type of evidence is that which provides direct proof of the truth of an assertion.
At the other extreme is evidence that is merely consistent with an assertion but does not rule out other, contradictory assertions, as in circumstantial evidence.
Level of Evidence#Evidence like Trust comes with a varying Level Of Assurance
Most often used within the Evidence Based Medicine (EBM) the order scientific levels of evidence are generally accepted across all scientific work Products with some differing numbers.
Levels of Evidence (sometimes called hierarchy of Evidence) are assigned to studies based on the methodological quality of their design, validity, and applicability to patient care. These decisions gives the "grade (or strength) of recommendation."
|Level of evidence (LOE)||Description|
|1||Evidence from a systematic review or meta-analysis of all relevant RCTs (randomized controlled trial) or evidence-based clinical practice guidelines based on systematic reviews of RCTs or three or more RCTs of good quality that have similar results.|
|2||Evidence obtained from at least one well-designed RCT (e.g. large multi-site RCT).|
|3||Evidence obtained from well-designed controlled trials without randomization (i.e. quasi-experimental).|
|4||Evidence from well-designed case-control or cohort studies.|
