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
Objective: To determine the prevalence of active myofascial trigger points (MTrPs) in office workers who sit for extended periods and use visual display terminals for ≥4 hours a day. Identify predictive factors associated with MTrP activation. Design: Cross-sectional study. Setting: Administration and services departments in municipal settings (January-August 2025). Participants: A total of 305 municipal volunteer employees (N=305; 133 men: 36.30±8.80y; 172 women: 37.59±9.44y) aged 18-65 years who worked at a video display terminal for ≥4 hours daily were included. Interventions: Not applicable. Main Outcome Measures: Participants completed the Neck Disability Index and Oswestry Disability Index. A physiotherapist specialized in myofascial pain assessed bilateral MTrPs in cervical and lumbogluteal muscles using standardized palpation and algometry. Logistic regression models were developed to identify predictive factors, and model performance was evaluated through receiver operating characteristic curve analysis. Results: Active MTrPs were found in 40% of participants in the right trapezius (25% men; 54% women), 35% in the left trapezius (18% men; 48% women), and 20% in the right sternocleidomastoid (9% men; 28% women), with consistently higher prevalence in women. Neck Disability Index and Oswestry Disability Index scores were identified as significant predictor factors (odds ratio>1), whereas higher pressure pain thresholds were protective (odds ratio<1). The models demonstrated good discriminative ability (area under the curve, 0.74-0.88) and high sensitivity (∼90%). Conclusions: Active MTrPs show high prevalence among office workers, particularly in women and the cervical region. Disability scores were associated with increased MTrP activation, whereas higher pressure pain thresholds were linked to lower activation. These findings suggest that incorporating algometry into musculoskeletal assessments and strengthening programs for cervical, scapular, and lumbar muscles may help prevent myofascial pain and disability in sedentary workers.
