    The systematic review evaluated the efficacy of nebulized epinephrine for treating croup in children through a meta-analysis of 12 studies.

  • 2

    Nebulized epinephrine significantly reduced croup severity scores 30 minutes post-administration, but this effect was not sustained at 2 hours.

  • 3

    The analysis included 325 patients receiving treatment and 347 controls, with no significant reduction in hospital stay observed (P = 0.07).

  • 4

    The study was registered in PROSPERO and followed PRISMA 2020 guidelines, ensuring methodological rigor in the systematic review process.

  • 5

    Current evidence does not support the routine use of nebulized epinephrine to shorten hospitalization for croup, despite its role as an early intervention.
