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

backgroundThe prevalence of conditions necessitating anticoagulation therapy among pregnant women has been steadily increasing. Although low-molecular-weight heparin (LMWH) is commonly used, several studies have investigated the use of fondaparinux in pregnant women. However, the safety profile of fondaparinux in this population remains to be fully elucidated.

methodsA comprehensive literature search across ten databases was conducted in September 2024. This meta-analysis was conducted following the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines for systematic reviews of observational studies. Dichotomous data from eligible studies were combined using the Mantel‒Haenszel model. Standard mean differences with 95% confidence intervals were assessed. Heterogeneity was evaluated using I

resultsNine studies met the inclusion criteria. Based on the GRADE approach, the quality of evidence ranged from very low to low. Fondaparinux did not increase the incidence of bleeding-related adverse events (vaginal bleeding: OR = 0.99, 95% CI 0.43-2.30, P = 0.98; postpartum haemorrhage: OR = 0.35, 95% CI 0.07-1.73, P = 0.20). Fondaparinux was associated with reduced risks of hepatic transaminase elevation (OR = 0.20, 95% CI 0.08-0.49, P < 0.01), gastrointestinal reactions, allergies, and injection site skin reactions (OR = 0.19, 95% CI 0.09-0.41, P < 0.01).

conclusionThe findings of this systematic review and meta-analysis suggest that the use of fondaparinux among pregnant women has certain advantages. However, these conclusions warrant further validation through high-quality, large-scale studies conducted in multiple countries. (PROSPERO-CRD42024591579).
