Level of Evidence
Level of evidence, which is also referred to as the hierarchy of evidence, is the rank that
is used to categorize the comparative strength of results attained from scientific studies. The
various levels of evidence are based on quality, applicability, validity and methodology among
others. The following are the various type of level of evidence;
Level 1- These are evidence from a systematic evaluation or meta-analysis of all pertinent
RCTs (randomized controlled trials). For instance, a patient under this stage is
randomly
assigned to the control group or treatment (Burns, Rohrich & Chung, 2012)
.
Level II- this is evidence obtained from a small and well-organized randomized
controlled trial — for instance, a large multi-site randomized controlled trial.
Level III- Evidence gained from well-made controlled trials lacking randomization. For
instance,
quasi-experimental in the research (
Wagner et al., 2017).
Level IV- Evidence from organized case-control or historical cohort research. For
instance, comparison and reference studies in two different people.
Level V- Evidence from methodical evaluations of descriptive and qualitative research.
For instance, meta-synthesis or evidence based on physiology or expert opinion.
Additionally, common Level V evidence is
encyclopedias, textbooks, and handbooks
among others. This stage incorporates a systematic evaluation that utilizes quantitative
approaches to create conclusions from the result (Burns, Rohrich & Chung, 2012)
. The
systematic reviews and meta-analysis are perceived to be the most important and

evidence-based levels as they incorporate a high degree of quantitative evaluation, severe
scientific approaches, reviews and analysis.
