Effect of study parameters on stenosis of coronary artery.
| Parameter | Betaa | Standard error | Wald | P value | Odds ratio (OR) |
|---|---|---|---|---|---|
| Sex (female 1, male 2) | 1.406 | 0.622 | 5.1 | 0.025 | 4.08 |
| Age (year) | 0.05 | 0.026 | 3.6 | 0.05 | 1.05 |
| BMIb | − 0.033 | 0.058 | 0.32 | 0.56 | 0.96 |
| LDL (mg/dl) | 0.034 | 0.014 | 6.01 | 0.014 | 1.03 |
| TG (mg/dl) | − 0.001 | 0.005 | 0.056 | 0.81 | 0.99 |
| Cholesterol (mg/dl) | 0.005 | 0.005 | 1.039 | 0.3 | 1.01 |
| GPX1 activity (U/gr Hb) | − 0.023 | 0.017 | 1.73 | 0.18 | 0.97 |
Based on the P and OR values, the sex, age and LDL changes related directly (Beta > 0) and significantly (P value < 0.05) to the stenosis of coronary arteries.
a
Beta, regression model coefficient.
b
BMI (body mass index): 1, under-nutrition; 2, normal; 3, overweight; and 4, obese.
