Weighted linear regression for the components of the z-score in coffee intake group.
| Components | 0–2 Cups/day (Ref. = Nondrinker) | >2 Cups/day (Ref. = Nondrinker) | ||
|---|---|---|---|---|
| Coefficient (95% CI) | p | Coefficient (95% CI) | p | |
| BMI (kg/m2) * | −0.7 (−1.37 to −0.09) | 0.03 | −0.7 (−1.30 to −0.10) | 0.02 |
| HDL (mg/dL) | −1.80 (−4.81–1.22) | 0.24 | −0.34 (−3.14–2.46) | 0.81 |
| Fasting glucose (mg/dL) | −0.13 (−0.42–0.17) | 0.4 | −0.22 (−0.48–0.05) | 0.11 |
| Triglyceride (mg/dL) | 3.65 (−13.47–20.76) | 0.68 | 7.64 (−9.96–25.25) | 0.39 |
| SBP (mmHg) | −1.38 (−4.89 −2.14) | 0.44 | −3.58 (−6.69 to −0.46) | 0.02 |
* Adjusted for age, gender, education level, total energy intake, PIR, HOMA-IR, smoke status, triglyceride, total cholesterol, waist circumference and use of glucocorticoid. BMI, body mass index; HDL, high density lipoprotein; SBP, systolic blood pressure; CI, confidence interval; Ref., reference. A β-coefficient was calculated by weighted linear regression for BMI, HDL, fasting glucose, triglyceride and SBP, respectively.
