Table 5 Interaction between pBMI and TG levels for the risk of GDM*
TG levels | Non-overweight (pBMI < 23.00) | Overweight (pBMI ≥ 23.00) | OR (95%CI) for risk ratio within category of blood lipid levels | AP (95%CI) | RERI (95%CI) | ||
|---|---|---|---|---|---|---|---|
GDM/Control (n) | OR (95%CI) | GDM/Control (n) | OR (95%CI) | ||||
Low levels (< 2.30) | 72/397 | 1.000 | 60/204 | 4.771 (2.961–7.688) P < 0.001 | 4.771 (2.961–7.688) P < 0.001 | 0.203 (-0.229–0.635) P = 0.357 | 1.370 (-1.958–4.698) P = 0.420 |
High levels (≥ 2.30) | 45/51 | 1.610 (1.097–2.363) P = 0.015 | 55/44 | 6.751 (4.203–10.843) P < 0.001 | 4.164 (2.540–6.826) P < 0.001 | ||
OR (95% CI) for high TG levels within category of pBMI |  | 1.610 (1.097–2.363) P = 0.015 |  | 1.437 (0.815–2.532) P = 0.210 |  | ||
