The topic: Discuss the difference between levels of evidence 2 & 3
the student’s post:
A variety of evidence hierarchies exist to evaluate the level of evidence. To apply these hierarchies, nurses must have a working knowledge of research design (Glasofer el at., 2019). Level 2 Quasi-experimental Study. Systematic review of a combination of RCTs and quasi-experimental, or quasi-experimental studies only, with or without meta-analysis. Level 3 Non-experimental study. It’s an observational analytic design. Systematic review of a combination of RCTs, quasi-experimental and non-experimental, or non-experimental studies only, with or without meta-analysis. Cohort study with control group. Regards,
