Correlation between multiple embryo transfers and the incidence of preterm birth and low birth weight: a network meta-analysis.
Article in Archives of gynecology and obstetrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
purposeIn vitro fertilization and embryo transfer (IVF-ET) has become crucial for infertile couples. Previous studies have suggested that multiple ETs are associated with increased risks of preterm birth and low birth weight. The current study aims to investigate this association.
methodsPubMed, Cochrane Library, EMBASE, ScienceDirect, and China National Knowledge Infrastructure databases were systematically searched. Network meta-analysis was performed to compare the associations between different numbers of embryo transfers (≥ 2) and the incidence rates of preterm birth and low birth weight. Consistency and inconsistency models were applied to ensure reliability. Frequentist statistical methods used data integration. The surface under the cumulative ranking curve (SUCRA) value was used to rank the risks of preterm birth and low birth weight associated with varying numbers of ETs.
resultsThere was a significant difference in the incidence of low birth weight between the 2-ET and 4-ET groups. The 4-ET group had the highest risks for preterm birth and low birth weight.
conclusionMultiple ETs are associated with increased risks of preterm birth and low birth weight. This study highlights the need for tailored clinical strategies to optimize pregnancy outcomes and mitigate complications.
