Comparison of clinical characteristics between RA patients on a low-salt diet versus RA patients on a high-salt diet
| Low-Salt Diet RA patients (n = 7) | High-Salt Diet RA patients (n = 12) | p-Value | |
|---|---|---|---|
| p-SGK1 Relative Expression (mean ± SD) | 0.54 ± 0.11 | 0.66 ± 0.10 | 0.020 |

| Number of Tender Joints (mean ± SD) | 3.71 ± 1.11 | 6.17 ± 2.25 | 0.016 |
| Number of Swollen Joints (mean ± SD) | 1.71 ± 1.80 | 3.67 ± 2.50 | 0.089 |
| ESR (mean ± SD) | 31.3 ± 8.20 | 39.92 ± 10.31 | 0.076 |
| DAS28-ESR (mean ± SD) | 4.21 ± 0.59 | 5.04 ± 0.64 | 0.013 |
| Disease Duration (months, mean ± SD) | 6.00 ± 1.92 | 6.75 ± 2.01 | 0.435 |
| RF Positive (%) | 85.7 | 75.0 | 1.000 |
| anti-CCP Antibody Positive (%) | 100 | 75 | 0.263 |
| Female (%) | 71.4 | 83.3 | 0.603 |

ESR: Erythrocyte Sedimentation Rate; DAS28-ESR: Disease Activity Score based on 28 Joints with ESR; RF: Rheumatoid Factor; anti-CCP Antibody: Anti-Cyclic Citrullinated Peptide Antibody. p < 0.05 indicates statistically significant difference.
