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: To develop and report the psychometric properties of a comprehensive scale designed to measure stereotypes and attitudes of the general population towards people with Parkinson's disease (PwP). Methods: The development and analysis of the Parkinson's Disease Stigma Perception scale (PDSP) included four phases: 1) literature review, 2) item development, 3) tests of validity and reliability, and 4) dissemination of a preliminary version. Internal consistency was assessed using Cronbach's alpha, exploratory factor analysis (EFA) to explore underlying structures, and confirmatory factor analysis to test the model's fit. Results: Six (2%) of the 294 survey respondents were disqualified because of incomplete data. The mean age was 38.3±15.9 years, 70.1% were women, and mean education was 16.5±3.37 years. EFA identified three factors with eigenvalues >1 (social avoidance and negative attitudes, prejudice and discrimination, and stereotypes). A root mean square error of approximation of 0.07 indicated acceptable fit, while a comparative fit index of 0.90 suggested adequate fit. Cronbach's alpha and McDonald's omega yielded 0.74 and 0.83, respectively, with low floor effects (2.4%) and no ceiling effect. Item-total correlations ranged from 0.30 to 0.60 (p<0.001). Conclusions: The PDSP demonstrated reliability and validity in assessing stigmatizing attitudes towards PwP. Future studies can further explore the scale's impact and its applicability across various contexts.
