Comparison of tHCY, eGFR, folic acid, and vitamin B₁₂ levels in controls and subgroups of IS patients with different renal function. A. tHCY level was higher in IS patients with NR or RI than in controls. B. eGFR was higher in nLAA and nSAO patients but was lower in IS patients with RI compared with controls. C. Folic acid level was lower in IS patients with NR or RI than in controls. D. Vitamin B₁₂ level was lower in IS patients with NR or RI than in controls, except for the nLAA subgroup. Compared with control group, #P<0.05, *P<0.01.
