Table 3. Multivariate stepwise linear regression analysis with Ln insulin sensitivity index (ISIOGTT) as dependent variable.
Independent variable | Beta coefficient | Standard error | t | p value |
Fasting proinsulin a | −0.365 | 0.065 | −5.225 | <0.001 |
Adiponectin a | 0.295 | 0.006 | 4.008 | <0.001 |
hsCRP a | −0.236 | 0.017 | −3.268 | 0.001 |
TG a | −0.162 | 0.058 | −2.171 | 0.032 |
SPARC a | −0.156 | 0.052 | −2.201 | 0.030 |
Independent variables included in the model were pre-BMI, gestational age, systolic blood pressure, triglycerides, SPARC, adiponectin, fasting proinsulin, hsCRP, WBC count and ALT. a Skewed distributions were logarithmically transformed for analysis. ISIOGTT: insulin sensitivity index; hsCRP, hypersensitive C reaction protein; TG, triglyceride; SPARC, secreted protein acidic and rich in cysteine.
