CH VS Normotensive
Three studies (269259 twin pregnancies) explored the risk of birthweight
discordance (≥15%) in twin pregnancies affected by CH compared with
Normotensive group. Overall, twin
pregnancies affected by CH were at a higher risk of birthweight
discordance (OR 1.59, 95% CI 1.46-1.73; I2 =3%).
