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

BACKGROUND AND

objectivesThe Fontan operation is a significant advancement in the palliative treatment of patients with single ventricular physiology. However, pregnancy in women with Fontan circulation presents increased risks for both the mother and fetus, with limited data available on maternal and fetal outcomes. This study reports maternal and fetal outcomes of pregnancies in women with Fontan circulation from a single tertiary center.

methodsThis retrospective study included all pregnant patients with Fontan physiology treated at Seoul National University Hospital from June 1986 to September 2023. The cases reviewed encompassed miscarriages, premature births, and full-term deliveries.

resultsEight patients underwent 15 pregnancies. The mean age at first pregnancy was 26.7 years. There were 7 live births (46.7%) and 8 miscarriages (53.3%), including 1 therapeutic miscarriage. The average age at first delivery was 28 years and the mean gestational age was 36

conclusionsWe observed a 46.7% success rate of live births among pregnant women with Fontan circulation. Although 2 pregnancies had cardiac complications, there was no severe morbidity and mortality. Thus, pregnancy and planned delivery are feasible in selected women with Fontan circulation under close monitoring.
