What is meant by critical appraisal process in randomized control trial?
Critical appraisal is an essential skill for evidence-based practitioners. It involves the systematic examination of research in order to assess its trustworthiness and relevance to specific situations. This article gives an overview on how to approach critical appraisal of randomized controlled trials.
What level of evidence is a non randomized control trial?
Evidence consisting of a non-blinded, non-randomized trial (i.e., a phase II study) may be considered as Level 2 evidence in some cancer-related cases (i.e., rare cancers or cancers with limited available treatment options).
What level of evidence is a cohort study?

| Level IV | Evidence from well-designed case-control or cohort studies. |
What are the three main purposes of the critical appraisal process?
The quantitative research critical appraisal process includes three steps: (1) identifying the steps of the research process in studies; (2) determining study strengths and weaknesses; and (3) evaluating the credibility and meaning of study findings.
How do you structure a critical appraisal?
The critique should be a balanced discussion and evaluation of the strengths, weakness and notable features of the text. Remember to base your discussion on specific criteria. Good reviews also include other sources to support your evaluation (remember to reference). You can choose how to sequence your critique.

What type of research is a cohort study?
Cohort studies are a type of longitudinal study—an approach that follows research participants over a period of time (often many years). Specifically, cohort studies recruit and follow participants who share a common characteristic, such as a particular occupation or demographic similarity.

Rather, cohort studies are largely about the life histories of segments of populations and the individual people who constitute these segments.
