Table 3. Factors related to non-/reverse-dippers.
| Factors | Model 1 | Model 2 | ||||
|---|---|---|---|---|---|---|
| Multivariate OR | 95% CI | P value | Multivariate OR | 95% CI | P value | |
| Ca × P (per 1 mg2/dL2) | 1.212 | 1.041–1.411 | 0.013 | 1.249 | 1.053–1.482 | 0.011 |
| iPTH (per 1 pg/mL) | 1.008 | 1.002–1.014 | 0.013 | - | - | - |
| Albumin (per 1 g/dL) | 0.363 | 0.174–0.761 | 0.007 | - | - | - |
| Nighttime SBP (per 1 mmHg) | - | - | - | 1.042 | 1.022–1.062 | < 0.001 |
| Nighttime DBP (per 1 mmHg) | - | - | - | 1.040 | 1.010–1.070 | 0.008 |
Model 1: adjusted for P, Ca × P, iPTH, albumin, eGFR, and UPCR; Model 2: adjusted for P, Ca × P, iPTH, albumin, eGFR, UPCR, nighttime SBP, and nighttime DBP.
Ca = calcium, CI = confidence interval, DBP = diastolic blood pressure, eGFR = estimated glomerular filtration rate, iPTH = intact parathyroid hormone, OR = odds ratio, P = phosphorus, SBP = systolic blood pressure, UPCR = random urine protein/creatinine ratio.
