Table 3.
Stepwise multivariable regression analysis in the PWS group. sUA was tested as the dependent (continuous) variable. Independent variables tested in the equation were age (year), sex (females = 0, males = 1), obesity (BMI > 30 kg/m2), PWS karyotype (DEL15 = 0, UPD15 = 1), fat-free mass (FFM, kg), triglycerides (mg/dL), and HDL-cholesterol (mg/dL) levels.
| Dependent Variable | Independent Variables | Beta | T | p | Adjusted R2 |
|---|---|---|---|---|---|
| sUA (mg/dL) | FFM | 0.35 | 3.66 | 0.0001 | 0.19 |
| Triglycerides | 0.23 | 2.44 | 0.017 | ||
| Age | 0.18 | −1.93 | 0.056 | ||
| Karyotype | 0.10 | 1.06 | 0.3 | ||
| HDL | 0.11 | −1.05 | 0.3 | ||
| Sex | 0.08 | 0.72 | 0.4 | ||
| Obesity | 0.02 | 0.22 | 0.8 |
