From: Lowest nocturnal systolic blood pressure is related to heavy proteinuria and outcomes in elderly patients with chronic kidney disease

Figure 1

Influence of CKD stage and proteinuria on the lowest nocturnal systolic blood pressure (LNSBP). Quartile 4 represented superior proteinuria, and quartile 1 represented inferior proteinuria. Quartile 1: 24-h proteinuria < 0.5 g; Quartile 2: 0.5 g ≤ 24 h proteinuria < 1.8 g; Quartile 3: 1.8 g ≤ 24 h proteinuria < 4.0 g; Quartile 4: 24 h proteinuria ≥ 4.0 g.
