    The study examined the relationship between the red blood cell distribution width-to-albumin ratio (RAR) and in-hospital mortality in cardiac arrest patients.

  • 2

    A total of 2,508 cardiac arrest patients were analyzed, revealing a nonlinear relationship between RAR levels and in-hospital mortality.

  • 3

    Each one-unit increase in RAR was associated with a higher risk of in-hospital mortality, with an adjusted odds ratio of 1.16.

  • 4

    The association between RAR and mortality was stronger below the threshold of 5.354, indicating a significant nonlinear effect.

  • 5

    Hypertension was found to marginally modify the RAR-mortality association, while the positive correlation remained consistent across subgroups.
