iron(2+) — increases blood haemoglobin concentration
ModerateEvidence strength: moderate. Human evidence with one recorded weakness, or capped at moderate by its design or by unread numbers.Findingreplicated ×4“Use of iron was associated with significantly increased mean haemoglobin concentration in the third trimester or at delivery (mean difference 4.50 (3.62 to 5.39) g/L; I2=0%; 31 trials; supplementary figure 19) and in the postpartum period (7.01 (0.36 to 13.66) g/L; I2=0%; eight trials; supplementary figure 20) compared with no iron or placebo.”

iron(2+) — increases birth weight
ModerateEvidence strength: moderate. Human evidence with one recorded weakness, or capped at moderate by its design or by unread numbers.Finding“Use of iron was associated with a significant increase in birth weight (mean difference 40.8 (0.97 to 80.6) g; I2=99%; 16 trials) and reduction in risk of low birth weight (relative risk 0.81, 0.71 to 0.91; I2=9%; 10 trials).”
