    This systematic review evaluated the prognostic value of psoas major muscle area in patients with peripheral arterial disease undergoing revascularization.

  • 2

    Seven retrospective cohort studies involving 2,290 patients were included, assessing the association between psoas major area and mortality.

  • 3

    Reduced psoas major muscle area was significantly associated with increased 1-year mortality (RR = 2.37; 95% CI 1.51–3.73; p < 0.001).

  • 4

    The analysis of 1-month mortality suggested a possible increase among sarcopenic patients, but the association was not statistically significant.

  • 5

    The study highlights the need for standardized definitions and prospective studies to clarify the role of psoas morphometry in clinical practice.
