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
Background: Eye care is crucial for maintaining healthy vision. This study aimed to design a determinants assessment instrument related to eye self-care in the student community and evaluate its psychometric properties. Materials and Methods: The present mixed-method cross-sectional study was conducted in two sections using Creswell and Plano Clark methods for instrument development. The study was conducted in Isfahan, Iran, in 2021. The first section (textual analysis and qualitative research) explained and developed the instrument's fundamental items. This section included in-depth, semi-structured interviews with 21 students and eight experts. In the second, the psychometric properties of the designed instrument have been evaluated. Twenty students assessed the instrument's qualitative and quantitative face validity. The instrument's content was measured by computing the content validity ratio and content validity index. In addition, exploratory factor analysis (performed on 251 students) was used to establish construct validity. Internal and test-retest reliability was determined using Cronbach's alpha and intraclass correlation coefficients (ICC), respectively. Results: During face and content validity assessment, a 39-item questionnaire was finalized. Exploratory factor analysis led to the extraction of seven factors, including "perceived self-efficacy and self-regulation," "outcome expectation," "perceived barriers," "motivation," "perceived susceptibility," "normative beliefs," and "perceived severity." The seven extracted factors explained 48.6% of the total variance. Cronbach's alpha was obtained to be 0.780, indicating good internal consistency, and the ICC for the total score of the questionnaire was 0.892 (95% confidence interval: 0.822-0.944), indicating excellent test-retest reliability. Conclusion: Our developed questionnaire was a valid and reliable instrument for assessing eye care determinants among students, a vulnerable population afflicted with eye defects and disorders.
