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 and Aims: The shoulder pain and disability index (SPADI) is a commonly utilized outcome measure. The study aimed to evaluate the reliability and validity of the Bengali version of the SPADI among patients with frozen shoulder. Methods: The SPADI was administered to 103 patients with frozen shoulder receiving physiotherapy at Centre for the rehabilitation of the paralyzed (CRP), a well-known rehabilitation hospital in Bangladesh. Among these patients, 31 underwent a retest after 15 days. To evaluate the construct validity of the SPADI, the scores were compared with other outcome measures, including the disabilities of the arm, shoulder, and hand questionnaire (DASH), the numerical pain rating scale (NPRS), and the 36-item short form health survey (SF-36). Structural validity was assessed using a two-factor confirmatory factor analysis (CFA). Additionally, the study analyzed internal consistency, test-retest reliability, and measurement error. Results: This study validated the Bengali version of the SPADI for frozen shoulder (FS). It showed strong psychometric properties, including high internal consistency (pain Conclusion: The Bengali version of SPADI showed good reliability and validity in a group of patients with frozen shoulder. This means that it is a dependable and accurate tool for measuring shoulder pain and disability in these patients.
