Association between morning home, evening home and office SBPs and the risk of decline in renal function. The model among patients with normal eGFR (⩾60 ml min−1 per 1.73 m2) at baseline was adjusted for baseline eGFR. The model among patients with low eGFR (<60 ml min−1 per 1.73 m2) at baseline was adjusted for age and family history of hypertension. The P-level for linear trend is indicated above the bars. The numbers inside the bars indicate 95% confidence intervals. The lowest BP category was treated as the reference category. eGFR, estimated glomerular filtration rate; SBP, systolic blood pressure.
