    RESUMEN Introducción: Existe una preocupación creciente entre los clínicos y los investigadores de que muchos resultados publicados en revistas científicas se tratan de falsos positivos. Objetivo: Determinar el valor de evidencia o integridad del cuerpo de la literatura publicada sobre la eficacia de pregabalina, gabapentina y duloxetina en el tratamiento del dolor neuropático. Métodos: Se realizó una búsqueda bibliográfica seleccionando ensayos clínicos aleatorizados que evaluaban la eficacia de pregabalina, gabapentina y duloxetina en dolor neuropático. Se aplicó el análisis de curva-p de los estudios con resultados estadísticamente significativos para estudiar su distribución. Resultados: Se demostró que existía una asimetría significativa a la derecha en la curva-p de los tres fármacos (test continuo p < 0,0001) confirmando el valor de evidencia de los estudios. Conclusiones: Los clínicos, los científicos y las publicaciones científicas deben ser conscientes del problema creciente con el "p-hacking" y sus efectos perjudiciales. Todas las partes comparten la responsabilidad en mantener la integridad científica de la literatura publicada.

    ABSTRACT Introduction: There is a growing concern among clinicians and researchers that many results published in scientific journals are false positives. Objective: To determine the value of evidence or integrity of the body of the published literature on the efficacy of pregabalin, gabapentin and duloxetine in the treatment of neuropathic pain. Methods: A literature search was conducted selecting randomized clinical trials that evaluated the efficacy of pregabalin, gabapentin and duloxetine in neuropathic pain. The p-curve analysis of the studies with statistically significant results was applied to study their distribution. Results: It was demonstrated that there was a significant asymmetry to the right in the p-curve of the three drugs (continuous test p <0.0001) confirming the value of evidence from the studies. Conclusions Clinicians, scientists and scientific publications should be aware of the growing problem with "p-hacking" and its harmful effects. All parties share the responsibility to maintain the scientific integrity of the published literature.
