From: Renal function during long-term lithium treatment: a cross-sectional and longitudinal study
Prevalence of patients falling into different estimated glomerular filtration rate (eGFR) categories among subgroups exposed to lithium for different times. The last two available eGFR values were used to assign patients to the following eGFR categories: G1, both values higher than 89 mL/min/1.73 m2; G1/G2, one value within G1 and one within G2; G2, both values between 60 and 89 mL/min/1.73 m2; G2/G3a, one value within G2 and one within G3a; G3a, both values between 45 and 59 mL/min/1.73 m2; G3b–G5, both values lower than 44 mL/min/1.73 m2.
