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

Although extracorporeal membrane oxygenation (ECMO) is increasingly utilized, only a limited level of experience has been reported in postpartum cardiopulmonary failure. Ten critically ill postpartum patients who received ECMO were included between January 2010 and December 2018 in this retrospective observational study. The main indication for ECMO support was peripartum cardiomyopathy (n = 5), followed by postpartum hemorrhage (n = 2). Nine patients initially received veno-arterial ECMO, and one patient received veno-venous ECMO. Major bleeding occurred in six patients. The median number of units of red blood cells (RBC) transfused during ECMO was 14.5 units (interquartile range 6.8-37.8 units), and most RBC transfusions occurred on the first day of ECMO. The survival-to-discharge rate was 80%. Compared to the survival outcomes in female patients of similar age who received ECMO, the survival outcomes were significantly better in the study population (56% versus 80%, P = 0.0004). Despite the high risk of major bleeding, ECMO for patients with postpartum cardiac or respiratory failure showed excellent survival outcomes. ECMO is feasible in these patients and can be carried out with good outcomes in an experienced centre.
