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

objectiveWe aim to increase knowledge on pregnancy and delivery risks in vascular Ehlers-Danlos Syndrome (vEDS). Our outcomes can contribute to establishing future guidelines for pregnancy and delivery management in women with vEDS.

designRetrospective multicentre cohort study.

settingWomen with vEDS due to pathogenic/likely pathogenic (P/LP) COL3A1 variants are at increased risk for arterial dissection and pregnancy-related complications during pregnancy and delivery. POPULATION: Women with a P/LP COL3A1 variant were included from 2019 until 2021.

methodsGenetic and clinical data was collected through retrospective analysis.

main outcome measuresDescription of the genotype and pregnancy-related outcomes.

resultsWe collected information about 121 pregnancies of 43 women with vEDS, including nine women with a haploinsufficient variant. Neither uterine rupture nor life-threatening or fatal vascular events occurred in the perinatal period. The miscarriage rate was 19% (23/121) and 19.1% of the live births were preterm (18/94). Miscarriages were significantly more frequent in women with a glycine substitution in COL3A1 compared to other COL3A1 variant types (19/23, 82.6%, p = 0.018). Thirty-four women had a vaginal birth (79.1%), including 1/7 with known vEDS. Eight deliveries were complicated by severe perineal tears, and six by postpartum haemorrhage.

conclusionsNo pregnancy-related deaths, arterial dissections or uterine ruptures occurred in our cohort. Since no life-threatening events occurred during pregnancy and delivery, discouragement of pregnancy in all women with vEDS in current guidelines might be too strict. Based on these data, we propose a shared decision-making process.
