Notably, even in the final adjusted model (model 4), after adjustments for age, dialysis vintage, BMI, albumin, serum calcium, serum phosphate, hs-CRP, triglycerides, serum creatinine, blood urea nitrogen, diabetes, and cardiovascular disease, a higher PhA was still associated with lower risks of obesity (OR = 0.231, 95% CI: 0.127–0.421, p < 0.001, pBonferroni < 0.001) and SO (OR = 0.098, 95% CI: 0.048–0.200, p < 0.001, pBonferroni < 0.001), but not with sarcopenia (OR = 0.517, 95% CI: 0.218–1.223, p = 0.133, pBonferroni = 0.376) (Supplementary Table S1). Here, ALB is linked to obesity due to melanocortin 4 receptor deficiency.
