Absence of evidence is not evidence of absence
Abstract
When a study ends with statistically significant results we have to judge whether results are clinically relevant and useful in our daily practice. A “Negative” result of a study does not imply that this is the truth. This paper illustrates with an example that the absence of evidence does not equal evidence of absence.
