Non-caffeine metabolites correlated with the FLI. Correlations, expressed as Pearson coefficients, of total urinary coffee metabolites [(caffeine metabolites (Σcaffeine) and non-caffeine metabolites (Σncm)], expressed per kg of fat-free mass, with the fatty liver index (FLI), fibrosis and steatosis parameters measured by Fibroscan®, and with serum zonulin levels. The p value for each Pearson coefficient is shown alongside in parentheses.
| Liver Parameter | Correlation with Σcaffeine |
Correlation with Σncm |
|---|---|---|
| FLI | −0.1783 (p = 0.0789) | −0.2266 * (p = 0.0249) |
| Fibrosis (kPa) | −0.1090 (p = 0.2852) | −0.0646 (p = 0.5271) |
| Steatosis (CAP, db·m−1) | −0.0734 (p = 0.4728) | −0.0860 (p = 0.3996) |
| Zonulin (ng·mL−1) | −0.0804 (p = 0.4510) | 0.06918 (p = 0.5171) |
* = significant difference (p ≤ 0.05, Pearson correlation). Abbreviations: Controlled attenuation parameter (CAP).
