Summary of results: subgroup analyses for maternal hemoglobin
| Random effects model | ||||
|---|---|---|---|---|
| Effect of MMS versus IFA on hemoglobin (third trimester), g/L | n comparisons | Mean difference (95% CI) | P value (subgroup differences) | Included studies |
| Subgroup analysis by iron dose | ||||
| MMS 60 mg iron versus IFA 60 mg iron | 3 | −0.68 (−3.56, 2.20) | 0.78 | 12, 19, 28 |
| MMS 30 mg iron versus IFA 30 mg iron | 4 | 0.14 (−0.71, 0.99) | 20, 22, 27, 30 | |
| MMS 30 mg iron versus IFA 60 mg iron | 4 | −0.26 (−1.41, 0.89) | 21, 23, 30, 40 | |
| Subgroup analysis by differences in total iron intake between IFA and MMS | ||||
| Small difference IFA‐MMS (<1200 mg) | 7 | 0.17 (−0.85, 1.20) | 0.58 | 12, 19, 20, 22, 27, 28, 30 |
| Large difference IFA‐MMS (≥1200 mg) | 4 | −0.26 (−1.41, 0.89) | 21, 23, 30, 40 | |
