Figure 2. Linear regressions of F_β2M on potential determinants. Scatter diagrams present data from diabetics (DM, blue) and non-diabetic controls (CTRL, orange). The graphs plot F_β2M against (A) E_Cd/C_cr, (B) [β₂M]_s, and (C) eGFR. No relationships are evident in (A). Strong direct relationships are evident in both groups in (B). In (C), a direct relationship is evident in CTRL, but no relationship is evident in DM. Cd: Cadmium; cr: creatinine; β₂M: β₂-microglobulin; F_β2M: rate of glomerular filtration of β₂M; DM: group with diabetes mellitus; CTRL: control group without diabetes; E_Cd/C_cr: amount of Cd excreted per volume of glomerular filtrate; [β₂M]_s: serum concentration of β₂M; eGFR: estimated glomerular filtration rate.
