| Result by study group | Comparison between LNS and IFA group | Comparison between MMN and IFA group | ||||
|---|---|---|---|---|---|---|
| Variable | LNS | MMN | IFA | P‐valuea | Difference in means (95 % CI) b | Difference in means (95 % CI) b |
| 6 months postpartum SRQ score, mean (SD), n | 1.76 (2.73) n = 347 | 1.92 (2.75) n = 365 | 1.71 (2.67) n = 364 | 0.560 | 0.07 (−0.33 to 0.47) | 0.20 (−0.19 to 0.59) |
