Linear mixed model investigating the association between biochemical and clinical variables and systolic blood pressure over time
| Estimate ± SE | P‐value | |
|---|---|---|
| Creatinine (mg/dL) | −3.0 ± 2.2 | .17 |
| Sodium (mEq/L) | −0.03 ± 0.1 | .75 |
| Chloride (mEq/L) | −0.2 ± 0.08 | .04 |
| Phosphate (mg/dL) | 0.4 ± 0.4 | .34 |
| Total calcium (mg/dL) | 0.6 ± 0.6 | .30 |
| Potassium (mEq/L) | 0.6 ± 1.1 | .56 |
| Cholesterol (mg/dL) | 0.02 ± 0.009 | .04 |
| PCV (%) | 0.30 ± 0.10 | .001 |
| Albumin (g/dL) | 4.5 ± 1.8 | .013 |
| Weight (kg) | 0.08 ± 0.07 | .27 |
| Heart rate (bpm) | 0.07 ± 0.01 | <.001 |
PCV, packed cell volume; SE, standard error.
Values depicted in bold were significantly associated with SBP in the univariable analysis and were included in the multivariable linear mixed model. PCV and heart rate remained significantly associated with SBP.
