1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundRecurrent implantation failure (RIF) has a multifactorial etiology. An umbrella review was undertaken to evaluate the multiple proposed interventions.

objectivesTo summarize and assess the strength of evidence of interventions for RIF from published systematic reviews (SR) of randomized clinical trials (RCTs). SEARCH STRATEGY: After prospective registration (PROSPERO CRD42023414255), a systematic search was conducted in the Cochrane Library, Scopus and Medline from inception until March 2024. SELECTION CRITERIA: SRs of RCTs, with or without meta-analyses (MA), were included if they reported clinical pregnancy rates (CPR) or live birth rates (LBR). DATA COLLECTION AND ANALYSIS: The methodological quality of the included SRs was appraised independently in duplicate using the AMSTAR 2 tool. For each intervention, the MAs of RCTs with statistically significant improvements were counted as a percentage of the total assessing the strength of evidence using the GRADE system. MAIN

resultsA total of 47 SRs were included: 32 reviews covered immunomodulatory interventions, 10 (68 RCTs) covered uterine and endometrial interventions, one covered antibiotics, and four (69 RCTs) addressed mixed approaches, including laboratory interventions. 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-analytic evidence of high-moderate GRADE strength: Granulocyte colony-stimulating factor (G-CSF) 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-rich 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%).

conclusionsEvidence syntheses of RCTs evaluating interventions for RIF suggest a consistent direction, with high to moderate strength, indicating that immunomodulatory treatments, including G-CSF, 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.
