From: Kidney function and dementia risk in community-dwelling older adults: the Shanghai Aging Study
Subgroup analysis of the association of low or moderate glomerular filtration rate (GFRcycys) versus high GFRcycys with onset of dementia in fully adjusted model in the Shanghai aging population. Points and error bars represent point estimates and 95% confidence intervals, respectively. T1 (low GFR, Tertile1), GFRcycys < 67 ml/min/1.73 m2; T2 (moderate GFR, Tertile2), 67 < =GFRcycys < 80 ml/min/1.73 m2; T3 (high GFR, Tertile3), GFRcycys > =80 ml/min/1.73 m2; HBP, hypertension; DM, diabetes; Hcrea, serum creatinine ≥ 75 μmol/l; Lcrea, serum creatinine < 75 μmol/l; E4p, E4 positive; E4n, E4 negative; HBMI, BMI ≥ 24 kg/m2; LBMI, BMI < 24 kg/m2; Old, age ≥ 70 years old; Young, age < 70 years old for interaction terms. Pinteraction was the result of interaction effect
