Fig. 3From: Fibroblast growth factor 21 (FGF21) is a sensitive marker of osteoporosis in haemodialysis patients: a cross-sectional observational studyCorrelation of serum FGF21 and albumin and L1 attenuation in osteoporosis group of HD patients. Log (FGF21) was significantly correlated with (a) albumin (r = -0.290, P < 0.05); (b) L1 attenuation (r = -0.238, P < 0.05). FGF21, fibroblast growth factor 21; Alb, albuminBack to article page
