Psychiatric Explanations of Poor Oral Intake: A Clinically Focused Review.
Review in Journal of the Academy of Consultation-Liaison Psychiatry. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPoor oral intake (POI) among medical-surgical inpatients can cause malnutrition and delay recovery due to medical consequences and the need for more invasive nutritional support. Many psychiatric conditions can cause POI; however, the role that psychiatric conditions play in POI has received limited attention to date.
objectiveThis review aggregates available information on POI due to psychiatric conditions and provides a framework for the clinical approach to these conditions in hospitalized adult patients.
methodsWe searched PubMed and EMBASE for reviews of POI due to psychiatric causes, but no relevant publications were identified. Diagnostic criteria for relevant conditions in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision and Rome IV were reviewed, as were C-L psychiatry textbooks and relevant society websites. This review was further supplemented by a case conference at the authors' institution.
resultsWe have divided results into five sections for clinical utility: (1) the need to rule out medical causes of POI; (2) unpleasant somatic experiences, including psychotropic causes; (3) mood, psychotic, catatonic, and neurocognitive disorders that can present with POI; (4) eating and feeding disorders; and (5) personal and interpersonal explanations of POI. Within each section, we review how to identify and manage each condition, specifically considering the effects of treatment on oral intake.
conclusionsThe clinical management of POI varies based on cause. For instance, psychostimulants can cause POI due to inappetence; however, they can treat POI due to abulia by improving motivation. The fact that such a broad range of psychiatric conditions can cause POI calls for a systematic clinical approach that considers the categories of potential causes. We also identified a need for prospective studies focused on the management of POI due to psychiatric conditions, as the literature on this topic is limited to case reports, case series, and retrospective cohort studies.
