3.3. Association of Low SMI and Clinical Outcomes
NRS
In a second step, we investigated the association of low SMI with different clinical outcomes (In addition, we also investigated the value of low SMI measured at L3 (current standard) with the same clinical outcomes (We also performed a subgroup analysis stratifying patients based on their risk for low SMI (i.e., patients ≥80 years of age and patients with NRS ≥ 4), which showed similar, mostly non-significant results. The results of the subgroup analyses are presented in the appendix (
