Resumen

Resumen:


Para lograr una adecuada comprensión de los resultados de un estudio de investigación en salud es importante tener claros ciertos conceptos epidemiológicos y estadísticos. El objetivo de este artículo es abordar, de manera sencilla y clara, los conceptos de número necesario a tratar (NNT) y número necesario para producir daño (NNH), explicar cómo se calculan, aclarar la importancia de su interpretación y aplicación en contextos clínicos a partir de ejemplos, al igual que algunas de las limitaciones de su uso que han sido frecuentemente discutidas en la literatura.


 

Keywords
