  • 1

    Higher creatinine muscle index reduces odds of probable sarcopenia.

  • 2

    The study evaluated 2,930 CKD patients across 16 centers.

  • 3

    Significant correlation with muscle strength and mortality rates.

  • 4

    Each 100 mg/day increase linked to lower death risk.

  • 5

    Observational design limits generalizability.

  • 6

    Creatinine muscle index easy to measure, warrants further investigation as a clinical tool.
