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

Compared to conventional autopsies, using postmortem fetal imaging techniques to investigate the cause of intrauterine fetal demise (IUFD) allows for shorter analysis times and increased consent rates from parents. We reported a case of IUFD in which postmortem fetal magnetic resonance imaging (MRI) was performed before delivery. We confirmed the umbilical abnormalities on MRI: a true knot, hypocoiled, and entangled with the fetal trunk. Notably, the umbilical cord entanglement observed on MRI had been released at the time of delivery. These MRI findings supported the umbilical cord abnormality as the probable cause of the IUFD. Postmortem intrauterine fetal MRI can identify umbilical cord entanglement before delivery, which could not otherwise be detected by conventional examinations. This case demonstrates the potential utility of postmortem intrauterine fetal MRI for evaluating the placenta and umbilical cord in IUFD cases.
