Petrified pinna and pericarditis in autoimmune polyendocrine syndrome.
Article in BMJ case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Petrified pinna refers to the calcification or ossification of the external auricular cartilage. It is an uncommon clinical entity and is most often associated with local trauma, frostbite or inflammation. Auricular calcification may be the exclusive cutaneous marker of underlying endocrinopathy. It has been most commonly associated with adrenal insufficiency and other endocrine conditions like diabetes mellitus, hypothyroidism and acromegaly. We present a 47-year-old Caucasian manwho presented with acute pericarditis with tamponade physiology, who was found to have petrified pinnae as a telltale sign of the underlying autoimmune polyendocrine syndrome type 2.
