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

Anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis is an autoimmune encephalitis, and 46% of women with anti-NMDAR encephalitis have tumors, of which 94% are ovarian teratomas. Patients with anti-NMDAR encephalitis rarely have extra-ovarian teratomas, particularly extra-ovarian mature cystic teratomas arising from the retroperitoneum. We herein report a 27-year-old woman who was diagnosed with anti-NMDAR encephalitis caused by a teratoma arising from the retroperitoneum. In patients with anti-NMDAR encephalitis, it is important to perform a systemic search, including for extra-ovarian teratomas. Plasma exchange significantly improved the patient's clinical symptoms.
