Effects of dietary assignment on serum urate, overall and by baseline serum urate concentration.
| Baseline, mean (SE) | End of period, mean (SE) | Change from baseline, mean (95% CI) | DASH versus control, mean (95% CI) | P | |
|---|---|---|---|---|---|
| Overall, N = 55 (161 measurements) | |||||
| Control, N = 28 | 5.35 (0.22) | 5.09 (0.21) | −0.26 (−0.50, −0.02) | Referent | Referent |
| DASH, N = 27 | 5.00 (0.23) | 4.69 (0.18) | −0.31 (−0.55, −0.07) | −0.05 (−0.39, 0.28) | 0.77 |
| Baseline serum urate < 6 mg/dL, N = 39 (115 measurements) | |||||
| Control, N = 18 | 4.68 (0.17) | 4.54 (0.19) | −0.13 (−0.45, 0.18) | Referent | Referent |
