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

Uterosacral ligament (USL) is an uncommon site of implantation for abdominal ectopic pregnancies. This is the first case of USL heterotopic pregnancy post invitro fertilisation (IVF). The patient presented 6 weeks after a double embryo transfer with acute onset abdominal pain and was diagnosed with a suspected live tubal ectopic pregnancy with a viable intrauterine pregnancy on ultrasound. A diagnostic laparoscopy revealed an ectopic pregnancy implanted on the left USL which was resected and confirmed on histology. The patient was discharged well on postoperative day 2 with a viable intrauterine pregnancy. This case highlights the importance of considering non-tubal heterotopic pregnancies in the context of risk factors including IVF with double embryo transfer presenting with abdominal pain.
