In order to preserve the clinical significance –considering that this was a retrospective report– the pain intensity was not assessed with a numerical scale as is usually the case, but with a categorical scale no pain, mild, moderate or severe pain.
Para mantener la significancia clínica y dado que es un reporte retrospectivo, la intensidad de dolor se valoró, no con una escala numérica como es usual, sino con una escala categórica no dolor, dolor leve, moderado o intenso.
