Nonlinear Relationship Between Monocyte‐to‐Lymphocyte Ratio and Bone Mineral Density in Type 2 Diabetes Mellitus: Mediating Role of Fat Distribution

Clin Endocrinol (Oxf)Published Cross-sectional study

Authors' conclusion

MLR is significantly associated with lumbar spine BMD in T2DM. Higher MLR levels correlated with reduced BMD. VSR plays a significant mediating role in this relationship, highlighting MLR's potential utility in osteoporosis diagnosis and importance of fat management for bone health.
