What level of evidence is a systematic review?
1
Demonstrated when there is clinical improvement from the treatment in the real-world context

experimental research
Regarding standard deviation, if you have a highly homogenous distribution of participant scores you will likely have a…
small standard deviation

META-ANALYSIS AND SYSTEMATIC REVIEWS Meta-analyses and systematic reviews that synthesize the results of multiple RCTs or experiments are the highest form of evidence.
Occurs if a first treatment condition affected participant performance on a second treatment condition.
carryover effect
Occurs if a research participant’s performance in a study was influenced by their awareness of being in research study.
hawthorne effect
A potential change in data that occurs sometimes from the beginning to the end of an experiment. These changes can arise due to factors such as participant fatigue or familiarity with assessment and/or intervention materials.
order effect
Clinical decision based on research evidence, clinical expertise, patient values and preferences, and clinical circumstances.
