Univariate associations of different diets and 24 h urinary parameters with urinary cystine excretion.
| Cystine | Coefficient B | 95% CI | p Value |
|---|---|---|---|
| Diet WD | (reference) | ||
| Diet MD | −13.91 | −50.33–22.52 | 0.454 |
| Diet VD | 9.40 | −35.65–54.46 | 0.682 |
| Sodium (70 mmol/24 h) | 0.04 | −0.41–0.49 | 0.853 |
| Sulfate (6 mmol/24 h) | −2.13 | −8.48–4.22 | 0.510 |
| Phosphate (10 mmol/24 h) | 4.77 | 1.71–7.83 | 0.002 |
Abbreviations: WD, Western-type diet; MD, balanced mixed diet; VD, balanced lacto-ovo-vegetarian diet; CI, confidence interval. The p values are from generalized models with a per-person random effect. The Coefficient B is the estimated difference in urinary cystine excretion per difference in univariate predictor.
