Fig. 4 — Predictive value of selected variables on annual changes in a TKV and b eGFR over 3 years. Data are based on multivariate regression analyses of tolvaptan-assigned patients in TEMPO 3:4 with TKV data available to calculate eHTKV-α at baseline and year 1 (n = 812); error bars represent 95% confidence intervals. BMI, body mass index; BP, blood pressure; eGFR, estimated glomerular filtration rate; eHTKV-α, estimated height-adjusted total kidney volume growth rate; St. β, standardised regression coefficient; TKV, total kidney volume
