Review in Innovations in clinical neuroscience, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06978803 (HYEEG Discourse in Psychosis), which is not on this map. Cited by 17 papers, 1 of them a synthesis that pooled it.

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.

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.

Abstract

Psychometric instruments are products of their time-Their designs and initial purposes are influenced and shaped by the contemporary treatment regimens, context, and cultural and conceptual biases of their developers. In this review article, the authors explore the history of the most influential schizophrenia research tools that have been created over the past several decades. The authors describe the scientific concepts, cultural influences, and challenges of past and present researchers as they strive to develop better assessment tools for schizophrenia. Starting with Moore's Scheme for the Quantitative Measurement of Abnormal Emotional Condition, developed in the early 1900s, and concluding with Kay, Fiszbein, and Opler's Positive and Negative Syndrome Scale, developed in the 80s, the authors describe several scales and illustrate how each scale led to and influenced the development of a later scale. The authors hope that a better understanding of schizophrenia assessment tool evolution and limitations will assist in the development of new instruments that better address the global needs for the evaluation, research, and treatment of psychosis.
