Multiple linear regression analysis for the effects of the study group (VNS vs. control), gender, age, and body mass index on the nonfasted blood glucose concentration (mg/dL) at the end of the follow‐up period.
| Parameter | Effect Size | Significance |
|---|---|---|
| Group (VNS = 1, control = 0) | N/A | n.s. |
| Gender (♂=1, ♀=0) | N/A | n.s. |
| Age (years) | +0.61 | P < 0.05 |
| BMI (kg/m2) | +0.78 | P = 0.09 |
| Baseline blood glucose (mg/dL) | +0.31 | P = 0.08 |
| Intercept | +53.56 | P < 0.01 |
The multiple linear regression analysis is based on 26 subjects (10 control, 16 VNS). The effects of group and gender were not significant and were removed from the model. Model statistics: multiple R 2: 0.42; adjusted R 2: 0.34; F: 5.326 on 3 and 22 degrees of freedom; P < 0.01. N/A: not applicable; n.s.: not significant.
