Construct Validity of the Pictogram Test for Diagnosis of Schizophrenia.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo examine construct validity of the Pictogram Test (PT) which assesses disturbances in thinking in individuals with schizophrenia. The PT was developed in Russia; it was found to be applicable for the English-speaking population of the USA. The variables of the PT were correlated with Minnesota Multiphasic Personality Inventory (MMPI-2).
methodRussian-and English-speaking participants completed the PT and MMPI-2 in their native languages.
resultsThe PT variables that reflected attribute selection choice of intermediate concepts for memorization and the variables that were geometrical shapes had significant correlations with MMPI-2 scales linked to schizophrenia. This represents evidence of convergent validity. The same PT indices did not significantly correlate with most of the MMPI-2 scales that are not elevated in schizophrenia, representing some discriminant validity of the PT.
conclusionsThe less often the participants were able to connect target words with economical intermediate concepts, the higher were the elevations of schizophrenia-related scales. Also, the more abstract and remote their intermediate concepts, the less often they recalled targets. These findings give evidence of the validity of the PT in assessing the thinking of individuals with schizophrenia and related conditions.
