							OR (95% CI)	P value	OR (95% CI)	P value
Maternal or neonatal complications, N (%)	615 (38.6)	507 (38.6)	93 (38.8)	669 (42.0)	524 (41.0)	121 (48.6)	0.86 (0.80 to 0.94)	0.001	0.66 (0.47 to 0.95)	0.025

The number of maternal and neonatal complications per person, mean (SD)	0.50(0.74)	0.50(0.73)	0.51 (0.76)	0.54 (0.74)	0.52 (0.73)	0.60 (0.70)	0.93 (0.87 to 0.99)	0.035	0.86 (0.67 to 1.10)	0.244

All 29 maternal and neonatal complications were included into the combined maternal and neonatal complications in Table 2 to provide a comprehensive overview of the primary outcomes
We utilized generalized linear models with a logistic distribution link to analyze maternal and neonatal complications. Additionally, a Poisson regression model was employed to assess the number of maternal and neonatal complications per person
Abbreviations: GDM Gestational diabetes mellitus, OR Odds ratio, IRR Incidence rate ratio
^aThe intervention effect for all pregnant women or pregnant women with GDM was adjusted for hospital, and a statistical significance level of P < 0.05 (two-sided) was used for all pregnant women, while a significance level of P < 0.025 (with Bonferroni correction) was used for pregnant women with GDM
