Pocas veces se toma en cuenta el conocimiento previo, y esta omisión conduce, no sólo a contentarse con una simple descripción cuando se necesitan recursos más complejos, sino también a utilizar ornamentos analíticos superfluos.  Desarrollo:  El conocimiento previo puede resumirse en una perspectiva analítica, que a su vez puede concretarse en 3 verbos clave: explorar, confirmar o verificar. Estos 3 verbos son determinantes a la hora de elegir el diseño y los recursos analíticos, aunque no se hagan explícitos al formular los objetivos de la investigación. Conclusiones: Salvo en las investigaciones de desarrollo, cuyo propósito es la obtención de un producto tangible, en la investigación hay siempre una perspectiva subyacente, que puede ser exploratoria o confirmatoria, y en este último caso puede orientarse a aportar apoyo empírico a una conjetura o a verificar hipótesis, que han sido previamente fundamentadas sobre bases teóricas o empíricas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Introduction: The importance of prior knowledge is argued, together with the objectives, the nature of the data and the type of design, in the choice of analytical resources in biomedical and health research. Prior knowledge is seldom taken into account, and this omission leads not only to contenting ourselves with a simple description when more complex resources are needed, but also to using superfluous analytical ornamentation.  Development: Prior knowledge can be summarized in an analytical perspective, which in turn can be specified in 3 key verbs: explore, confirm or verify. These 3 verbs are decisive when choosing the design and analytical resources, although they are not made explicit when formulating the research objectives. Conclusions: Except in development research, whose purpose is to obtain a tangible product, in research there is always an underlying perspective, which can be exploratory or confirmatory, and in the latter case it can be aimed at providing empirical support for a conjecture or a verify hypotheses, which have been previously founded on theoretical or empirical grounds.]]></p></abstract>
