Table 2
Logistic regression analysis after controlling simultaneously for potential confounders of predictors for antenatal insulin treatment (AIT).
| Independent variables | β-Coefficient | Odds ratio (95% CI) | values |
| Postprandial PG at 1-hr in 75 g OGTT | 0.165 | 1.179 (0.988–1.407) | 0.067 | Postprandial PG at 2-hr in 75 g OGTT | 0.053 | 1.054 (0.987–1.126) | 0.113 | Number of abnormal values in 75 g OGTT | 0.420 | 1.521 (0.207–11.201) | 0.680 |
| Forward selection method (conditional) | | | | Postprandial PG at 1-hr in 75 g OGTT | 0.109 | 1.115 (1.004–1.239) | 0.043 | Number of abnormal values in 75 g OGTT | 1.451 | 4.267 (0.669–27.228) | 0.125 |
| Backward elimination method (conditional) | | | | Postprandial PG at 1-hr in 75 g OGTT | 0.176 | 1.192 (1.006–1.413) | 0.042 | Postprandial PG at 2-hr in 75 g OGTT | 0.059 | 1.061 (0.998–1.127) | 0.057 |
