AMSTAR 2 appraised 41 (88%) SRs as critically low or low, and 6 (12%) as moderate or high in quality. The SRs often had a level of overlap of RCTs (median 33.3%), inconsistent definitions of RIF, and varied comparisons for the interventions. Considering the significant meta\u2010analytic evidence of high\u2010moderate GRADE strength: Granulocyte colony\u2010stimulating factor (G\u2010CSF) showed improvement in CPR in 9\/13 (69.2%) MAs and LBR in 1\/7 (14%); intralipid infusion showed improvement in CPR in 4\/6 (57.14%) MAs and LBR in 3\/4 (75%); peripheral blood mononuclear cells (PBMC) showed improvement in CPR in 4\/8 (50%) MAs and LBR 3\/5 (60%); platelet\u2010rich plasma (PRP) intervention showed improvement in CPR in 6\/10 (60%) MAs and LBR in 1\/5 (20%); human chorionic gonadotropins showed improvement in CPR in 3\/3 (100%) MAs; growth hormone showed improvement in CPR in 1\/1 (100%) MA; low molecular weight heparin showed improvement in CPR in 1\/1 (100%) MAs and LBR in 1\/2 (50%); hysteroscopy showed improvement in CPR in 1\/2 (50%) MAs; and, intentional endometrial injury showed improvement in CPR in 3\/4 (75%) MAs and LBR in 2\/3 (66.66%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Evidence syntheses of RCTs evaluating interventions for RIF suggest a consistent direction, with high to moderate strength, indicating that immunomodulatory treatments, including G\u2010CSF, PBMC, PRP, intralipid infusion, and intentional endometrial injury are likely to be effective. However, this conclusion should be interpreted with caution due to the generally low methodological quality of the included studies and the clinical heterogeneity observed in most SRs.<\/jats:p>\n
