Multivariate regression logistics analysis of kidney damage parameters of different SBP trajectory groups*
| Parameters of renal damage | Group | OR (95% CI) (n = 2949) |
|---|---|---|
| eGFR <60 ml·min−1·1.73 m−2 | Low-stable group | 1 |
| Moderate-stable group | 1.01 (0.55–1.85) | |
| Moderate increasing group | 1.05 (0.41–2.66) | |
| Elevated decreasing group | 1.05 (0.38–2.88) | |
| Elevated stable group | 3.04 (1.01–9.21) | |
| Positive urinary protein | Low-stable group | 1 |
| Moderate-stable group | 1.41 (0.86–2.29) | |
| Moderate increasing group | 2.23 (1.13–4.41) | |
| Elevated decreasing group | 3.58 (1.60–8.01) | |
| Elevated stable group | 2.16 (0.81–5.77) | |
| eGFR <60 ml·min−1 1.73 m−2 and/or positive urinary protein | Low-stable group | 1 |
| Moderate-stable group | 1.13 (0.76–1.68) | |
| Moderate increasing group | 1.41 (0.79–2.52) | |
| Elevated decreasing group | 2.08 (1.06–4.07) | |
| Elevated stable group | 2.55 (1.15–5.65) | |
| eGFR reduced ≥30% | Low-stable group | 1 |
| Moderate-stable group | 0.95 (0.57–1.57) | |
| Moderate increasing group | 1.27 (0.53–3.05) | |
| Elevated decreasing group | 1.09 (0.43–2.74) | |
| Elevated stable group | 4.32 (1.45–12.83) |
*Sensitivity analysis: Except people taking antihypertensive medications. With different BP trajectories as independent variables, low-stable group as the control group; adjusting for age, gender, SBP in 2006, FBG, BMI, eGFR, high cholesterol, smoking, alcohol consumption, physical activity, antihypertensive medications, slope of SBP. The same assignment as Table S1. BP: Blood pressure; eGFR: Estimated glomerular filtration rate; BMI: Body mass index; FBG: Fasting blood glucose; SBP: Systolic blood pressure; OR: Odds ratio; CI: Confidence interval.
