    The study identified four clinical subphenotypes of methicillin-resistant Staphylococcus aureus bacteremia (MRSAB) based on various clinical factors.

  • 2

    Subphenotype S2, characterized by older age and high comorbidity, had the highest 90-day mortality rate at 47.4%.

  • 3

    Cox regression analysis revealed significantly increased mortality risk for subphenotypes S2 and S4 compared to S1.

  • 4

    The study included 419 MRSAB patients from 15 Spanish hospitals, emphasizing the need for tailored treatment approaches.
