| 23 February 2011 | New citation required but conclusions have not changed | Three studies have been excluded: two (Tanbo 1990; Raneiri 1995) because gamete intrafallopian transfer (GIFT) has been removed from the comparisons, as this treatment is rarely used now, and one (Crosignani 1991) as only per‐cycle data were reported. Per‐cycle data from all comparisons have been deleted. One new study has been added to the comparison IVF versus unstimulated IUI (Elzeiny 2014). Two new studies have been added (Goldman 2014; Bensdorp 2015) to the comparison of in vitro fertilisation (IVF) versus intrauterine insemination plus ovarian stimulation (IUI + SO). One new study has been added to the comparison IVF versus IUI + clomiphene (Goldman 2014) |
