How does critical appraisal help nurses?
Critical appraisal helps clinicians understand the literature so they can implement it. Critical care nurses have a professional and ethical responsibility to make sure their care is based on a solid foundation of available evidence that is carefully appraised using the phases outlined here. Critical appraisal allows for decision-making based on evidence that demonstrates reliable outcomes. Any other approach to the literature is likely haphazard and may lead to misguided care and unreliable outcomes. 11 Evidence translated into practice should have the desired outcomes and their measurement defined from the body of evidence. It is also imperative that all critical care nurses carefully monitor care delivery outcomes to establish that best outcomes are sustained. With the EBP paradigm as the basis for decision-making and the EBP process as the basis for addressing clinical issues, critical care nurses can improve patient, provider, and system outcomes by providing best care.

What is the plausible range of values for the actual effect?
plausible range of values for the actual effect. For instance if the CI for a HR of 0.75 was 0.70-0.80 you could be comfortable saying that the true difference is likely somewhere between a 30% (0.70) and a 20% (0.80) relative reduction.By convention, when looking at ratios, if the CI doesn’t include 1.0 then the difference is considered statistically different and we believe there is a real difference. If the CI does include 1.0, that doesn’t mean there was no difference just that the difference is not considered a statistical difference. Some people think a CI means we are 95% confident that the result is in the interval, but this is not true. A CI is not a probability of the magnitude of an effect. It just means that if you did the study numerous times 95% of the CIs would contain the true result.
