The Neurology and Psychopathology of Pica.
Review in Current neurology and neuroscience reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
purpose of reviewPica is defined by the American Psychiatric Association's Diagnostic and Statistical Manual, 5th edition (DSM 5) as the ongoing ingestion of materials with no nutritive or food value. More specifically such ingestions must be unremitting for at least 1 month and occur at a developmentally inconsistent age for such behavior. This article reviews the association of pica with pregnancy, micronutrient deficiencies, psychiatric disorders, dementia, and developmental disorders with emphasis on autism spectrum disorders (ASD). RECENT
findingsSome variants of non-nutritive consumption are prevalent behavioral norms in non-western cultures, so not all picas should be considered pathological. However, the strong association of pica with iron deficiency anemia (IDA) lends credence to the hypothesis that dopamine transmission may be disrupted in this disorder. Picas associated with ASD are resistant to medications but can be treated with applied behavioral analysis therapy (ABA). Etiological hypotheses for pica are explored with a focus on neurobiological, neuroimaging, and psychiatric correlations. Pharmacological management and behavior modification strategies are also discussed. The possibility that pica is a form of addiction analogous to food cravings is introduced and suggested as an area for further research pursuits.
