Figure 2 Adjusted restricted cubic spline plots for all-cause mortality and serum folate concentrations. The potential confounders adjusted were as follows: age, sex, race, hypertension, physical activity, body mass index, eGFR, serum vitamin B12, albumin, serum glucose, phosphorus, uric acid, total iron binding capacity, folate as dietary folate equivalents, food folate.
Figure 3 Survival probability by the level of serum folate. Quintile categories of serum folate: Q1<8.7ng/mL, Q2 8.7–11.4ng/mL, Q3 11.5–14.6ng/mL, Q4 14.7–19.1ng/mL, Q5 ≥19.2ng/mL. The potential confounders adjusted were as the same as .
