Combined zinc and vitamin B6 deficiency in a patient with diffuse red rash and angular cheilitis 6 years after Roux-en-Y gastric bypass.
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 6 papers, 1 of them a synthesis that pooled 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.
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
A 39-year-old woman with a history of Roux-en-Y gastric bypass (RYGB) surgery and alcohol use presented with a confluent erythematous rash involving the perineum spreading outward to the abdomen, thighs and lower back. She had angular cheilitis and glossitis. The rash was painful and blistering in scattered areas. She was hypotensive and appeared to be in septic or hypovolemic shock at presentation. Serum levels of zinc and vitamin B6 were critically low and biopsy of her rash returned suggestive of a nutritional deficiency as its source. The rash slowly improved over the following 2 weeks with oral zinc and vitamin B6 replacement. The body rash resembled that of infants born with inherited defects in zinc transporters, referred to as acrodermatitis enteropathica (AE). This case may represent an acquired case of AE in the setting of prior RYGB.
