Temporomandibular Disorder in Domestic Waste Collectors: Cross-Sectional Study.
Article in Journal of oral rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMusculoskeletal disorders are prevalent among waste collectors, yet the temporomandibular disorder (TMD) assessment within this group remains overlooked.
objectiveThis cross-sectional study examined TMD in domestic waste collectors and its association with their work.
methodsThe study involved 288 adult men from a waste collection corporation, with 130 working in domestic solid waste collection (operational workers) and 158 in other roles (controls). TMD severity was assessed through inquiries about signs and symptoms. Missing teeth were clinically evaluated. Socio-demographic data, employment history, psychosocial factors, and severity of TMD were collected using a questionnaire.
resultsTMD was diagnosed in 47% of the operational workers, and the most reported TMD factors were self-perception of being a tense person (52.3%) and parafunctional habits (40.0%). In the whole sample, moderate/severe TMD was associated with alcohol dependence (OR = 3.51, 95% CI = 1.10-11.25, p = 0.03), and mild TMD was associated with parafunctional habits (OR = 3.36, 95% CI = 1.99-5.67, p < 0.001) and psychosocial factors (OR = 3.68, 95% CI = 2.17-6.25, p < 0.001). In operational workers, moderate/severe TMD was associated with alcohol dependence (OR = 4.84, 95% CI = 1.00-23.81, p = 0.05), and mild TMD was associated with age (OR = 2.60, 95% CI = 1.02-6.70, p = 0.05), psychosocial (OR = 4.41, 95% CI = 1.76-11.05, p = 0.002) and parafunctional (OR = 5.14, 95% CI = 2.17-12.19, p < 0.001) factors.
conclusionIn this sample of domestic waste collectors, moderate to severe TMD correlated with alcohol dependence, whereas mild TMD showed associations with age, psychosocial factors, and parafunctional habits. However, TMD did not exhibit a direct association with domestic waste-collecting work. Thus, addressing physical and mental health concerns within this occupational cohort may enhance overall well-being.
