Table 2. Mixed linear models for glycemic and cardiovascular biomarkers according to study group.
| Biomarker | 95% CI of the model Lower limit | 95% CI of the model Upper limit | 95% CI difference between intervention vs. placebo Lower limit | 95% CI difference between intervention vs. placebo Upper limit | p-value |
|---|---|---|---|---|---|
| Fasting glucose (mg/dL) | 81.632 | 184.132 | -78.612 | 84.405 | 0.944 |
| Estimated mean glucose (mg/dL) | 170.861 | 259.752 | -104.300 | 364.414 | 0.344 |
| HbA1c (%) | 5.960 | 9.043 | -3.632 | 1.269 | 0.344 |
| Insulin (µUI/mL) | 3.983 | 40.549 | -17.712 | 53.113 | 0.327 |
| HOMA-IR | 0.882 | 9.372 | -3.940 | 9.561 | 0.414 |
| HOMA-β | 0.761 | 9.273 | -3.522 | 8.331 | 0.318 |
| Urea (mg/dL) | 15.612 | 34.903 | -22.653 | 8.028 | 0.350 |

| Apolipoprotein B (mg/dL) | 99.598 | 138.216 | -48.552 | 12.865 | 0.254 |
| TyG Index | 8.865 | 9.880 | -0.502 | 1.112 | 0.459 |
95% CI : 95% confidence interval, HbA1c: glycated hemoglobin, HOMA-IR: Homeostatic Model Assessment for Insulin Resistance, HOMA-β = Homeostatic Model Assessment for β-cell function, TyG: triglyceride-glucose index.
The linear mixed models included group, time, and the group-time interaction, with repeated measurements nested within participants. The estimated difference corresponds to the comparison between the experimental group and the placebo group. The results should be interpreted as exploratory.
