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

Conjoined twins are a rare and complex anomaly of monozygotic twin gestations, in which there is joining of the bodies of two individuals. Prenatal imaging, including fetal MRI, plays a crucial role in prognostication and planning for these twins' families and multi-disciplinary medical teams. The ability of fetal MRI to provide large field-of-view imaging is well-suited to delineate the complicated shared and individual anatomy of these twins. In this review, we describe an approach to the fetal MRI of conjoined twins and its limitations, illustrate the fetal MRI findings of the conjoined twin morphological variants, and discuss common superimposed anomalies. The anatomic features most predictive of these twins' chances for survival and separation are also summarized.
