  • To enable the generation of relevant and robust biological insights.

Main Methods:

  • The study proposes nine guidelines for performing PEA.
  • Tips cover pre-analysis steps, result generation, and interpretation.
  • Guidelines are presented in an accessible manner for a broad audience.

Main Results:

  • The proposed tips aim to improve the quality and reliability of PEA outcomes.
  • Users can achieve more meaningful and robust results by applying these guidelines.
  • Enhanced PEA contributes to a better understanding of biological processes.

Conclusions:

  • Adherence to the nine tips can significantly improve pathway enrichment analysis.
  • These guidelines empower researchers, including students, to perform high-quality PEA.
  • Better PEA practices facilitate deeper biological discoveries.
