Figure 3. Mediation analysis of the association between eGFR, hemoglobin, and peak VO2.

Figure 3.

The path model and mediation analysis describing mediation of the relationship between eGFR and peak VO2 by hemoglobin are displayed. Path effects are reported as the change in peak VO2 per 1-SD decrease in eGFR (95% CI). The total effect of the association between eGFR and peak VO2 was −0.98 (95% CI: −1.41,−0.57). eGFR = estimated glomerular filtration rate; peak VO2 = peak oxygen consumption.
