Description 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.
Cuando un estudio finaliza con resultados estadísticamente significativos hay que juzgar si adicionalmente son clínicamente relevantes y útiles en nuestra práctica diaria. El hecho de encontrar en un estudio resultados “negativos” no implica que esa sea la verdad definitiva. Este artículo ilustra con un ejemplo porque la ausencia de evidencia no es igual a evidencia de ausencia.
