ReviewEating and weight disorders : EWD2020
A coin crisis: a case report of pica with minireview.
Review in Eating and weight disorders : EWD, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundPica is defined as a feeding and eating disorder where there is consumption of nonnutritive substances not consistent with cultural practices or social norms. Its aetiology is still unknown, as its prevalence and optimal treatment, which seem to vary with patients' characteristics and the specific behaviours involved.
objectivesThe authors present a case report of pica treated with copper supplementation, with further diagnostic and treatment considerations.
methodsClinical records and interviews were used. A review was conducted using PubMed database.
resultsA 59-year-old patient, diagnosed with paranoid schizophrenia, presented with sideroblastic anaemia secondary to zinc-induced copper deficiency in the context of pica. These behaviours ceased with copper supplementation. After 2-year remission, the patient was discontinued on oral copper. One week after, pica behaviours reoccurred, with further remission with renewed copper treatment. Based on temporal relationship, we propose that there might be an association between copper supplementation and pica, not related to its plasma levels.
conclusionsAs far as we know, this is the first case report in the literature with such a long-term follow-up of pica treatment. Our findings challenge the cause-effect relation between micronutrient deficiency and pica and prompts further research in the non-adaptive theories of this poorly understood clinical entity.
