Do not use epinephrine in digital blocks: A comprehensive review of epinephrine in the finger: Assessing the quality of reports of randomized clinical trials: Plastic surgery researchers need to consider utilizing a cohort or case-control design whenever an RCT is not possible.

Formulating Conclusions Based on Levels of Evidence The levels of evidence table found below used to summarize the findings are based on the levels of evidence developed by Sackett et al.

In addition, several cohort studies found no complications from the use of epinephrine in the fingers and hand.

Are the results of the study valid? A recent analysis looked at the number of level 1 studies in 5 different plastic surgery journals from — J Hand Surg Am.

So you want to be better: This example also demonstrates that RCTs are not feasible for rare events such as cancer and the importance of observational studies for a specific study question.
