1 · What the graph read from 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.

2 · The registry

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

purposeAutism, psychosis and catatonia were once considered part of schizophrenia. While both autism and catatonia have been "detached" from schizophrenia, co-occurrence of the three conditions may be suspected in some cases, because of overlapping features, leading to challenges in diagnosis and treatment. This review provides an overview of the literature regarding the co-occurrence of autism, psychosis and catatonia.

methodsA scoping review of peer-reviewed original research articles that simultaneously described all the three diagnostic constructs (autism, psychosis and catatonia) was performed. Using PRISMA-ScR guidelines, the review was based on MedLine, Scopus, PsycInfo and Cinahl databases. Studies included patients of all ages, races and both genders. A Qualitative Content Analysis (QCA) of the contents of the articles was also performed.

resultsSeventeen articles (n = 17) out of a total of 752 (after removing duplicates) met inclusion criteria, most of which (65%) were case reports/case series. Overall, majority of the studies lacked description of diagnostic procedures regarding psychosis - especially while describing co-occurrence of psychosis and catatonia in patients with autism. Reports of treatment outcomes showed considerable variations. Major themes identified in the QCA involved uncertainty, particularly in the differential diagnostic and treatment considerations.

conclusionThe results of this scoping review underscore a need for undertaking larger studies using structured diagnostic approaches for developing better methods to differentiate between autism, psychosis and catatonia. Our findings also point to a need for conducting treatment trials and developing treatment algorithms for mixed presentations when there is co-occurrence of autism, psychosis and catatonia.
