The impact of maternal 25[OH]D levels on neonatal birthweight. a The neonatal birthweight was significantly different between the maternal 25[OH]D status (deficiency group vs insufficiency group, P < 0.001; deficiency group vs sufficiency group, P = 0.011); b The neonatal birthweight discordance(%) was significantly different between the maternal 25[OH]D status (deficiency group vs sufficiency group, P = 0.016); c Maternal 25[OH]D levels were negatively correlated with the discordance in birthweight between cotwins, with the discordance in birthweight between cotwins decreased 2.67% when maternal 25[OH]D level increased by 1 ng/mL (95% CI: − 5.11, − 0.23. p = 0.032)
