meta-analysis
  • “In comparison to controls, the oral l-arginine groups showed significantly increased mean birthweight and gestational age (n = 8 and 5, respectively) in the total population.”
    Interests
    Industry funded
    Dose studied
    oral L-arginine 3 to 14 g/day, pooled; one trial gave 6.6 g/day with vitamins against vitamins alone
    Population
    Pregnant women in pooled randomised trials: at high risk of pre-eclampsia or with pre-eclampsia, gestational or mild chronic hypertension, with IUGR foetuses, or with threatened pre-term labour; controls received placebo, vitamins or no supplement
  • “In comparison to controls, the oral l-arginine groups showed significantly reduced risks of IUGR neonates, pre-term birth and respiratory distress syndrome (n = 7, 3 and 3, respectively) in the total population.”
