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
Introduction: Waste pickers are exposed to numerous occupational risks, including ergonomic risks. Objectives: To verify the occurrence of self-reported musculoskeletal disorders and associated risk factors among waste pickers working in sorting cooperatives. Methods: This cross-sectional study included a convenience sample of waste pickers from four cooperatives in metropolitan São Paulo, Brazil. Observations were made of their work environments and processes; a questionnaire was applied to characterize socioeconomic and organizational status, as well as the Nordic Musculoskeletal Questionnaire. After descriptive analysis, univariate and multivariate regression were used to identify risk factors associated with work-related pain and discomfort in the last 12 months. Results: A total of 250 waste pickers were included, mostly women (62%) aged 41 to 59 years (53%) who were Black or of mixed race (66.4%) and had low education. There was a high prevalence of musculoskeletal disorders among waste pickers from all cooperatives, with 163 (65%) reporting pain and discomfort. The cooperatives had similar production processes, but different structures and operating conditions. Working in a cooperative with worse infrastructure, prior work-related accidents, and having a prior occupation were identified as the main risk factors for musculoskeletal disorders. Conclusions: Cooperatives with precarious structure and working conditions partially explain the high proportion of waste pickers with musculoskeletal disorders, reinforcing the need for initiatives and policies to promote decent and safe work, thus improving the health and quality of waste pickers.
