- Early-screen Group (Type: EXPERIMENTAL): The early screening group will be screened by a 75g 2-hour oral glucose tolerance test (OGTT) at 18-20 weeks of gestational age (GA). The time of early screening and intervention will be 6-8 weeks earlier than that of standard screening and intervention.
- Standard-screen Group (Type: ACTIVE_COMPARATOR): The standard screening group will be screened by a 75g 2-hour oral glucose tolerance test (OGTT) at 24-28 weeks of gestational age (GA). The time of standard screening and intervention will be 6-8 weeks later than that of early screening and intervention.

Based on this trial design, predict the completion outcome and termination type (if applicable).
