| Estimated daily salt intake tertiles | P for trend | 1SD increment in estimated daily salt intake (2.0 g/day) | |||
|---|---|---|---|---|---|
| T1 (low) | T2 | T3 (high) | |||
| No. at risk | 338 | 338 | 338 | ||
| Mental distress with hypertension | |||||
| No. of cases (percentage) | 26 (7.7) | 21 (6.2) | 12 (3.6) | ||

| Mental distress without hypertension | |||||
| No. of cases (percentage) | 19 (5.6) | 8 (2.4) | 11 (3.3) | ||
| Age-adjusted OR | 1.00 | 0.40 (0.17–0.93) | 0.53 (0.25–1.14) | 0.082 | 0.67 (0.48–0.94) |

Multivariable OR: adjusted further for body mass index, systolic blood pressure, antihypertensive medication use, thyroid disease, alcohol consumption, stroking status, AST, triglycerides. HDI-cholesterol, HbAlc, antidiabetic medication use, and GFR. The median values of estimated daily salt intake tertiles were 7.0, 8.8, and 10.8 g/day
