1 · What the graph read from it

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.

2 · The registry

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: Dentistry is considered a high-risk profession for developing work-related musculoskeletal disorders (MSDs), particularly in the cervical region, due to prolonged static postures, repetitive movements, and sustained neck flexion during clinical procedures. Limited evidence exists regarding the early short-term effects of prolonged dental chair utilization on cervical spine mobility among dental interns. Objective: To evaluate changes in cervical spine range of motion (ROM) and neck pain associated with prolonged dental chair utilization among dental internship students Methods: A prospective short-term observational repeated-measures study was conducted among 40 dental internship students at Thumbay Dental Hospital, Gulf Medical University, Ajman, United Arab Emirates. Cervical ROM was assessed using a validated digital inclinometer for flexion, extension, bilateral lateral flexion, and bilateral rotation. Neck pain intensity was evaluated using the Visual Analogue Scale (VAS). Assessments were performed at baseline and repeated after one month of routine clinical exposure involving prolonged dental chair utilization. Paired-sample t-tests were used for statistical analysis, with significance set at p ≤ 0.05. Results: A statistically significant increase in neck pain intensity was observed following one month of clinical exposure (p < 0.05). Cervical ROM measures demonstrated no significant differences in flexion, extension, left rotation, or bilateral lateral flexion between baseline and follow-up assessments. However, right cervical rotation showed a statistically significant increase at follow-up. These findings suggest that short-term occupational exposure primarily affects pain perception before substantial mobility impairment develops. Conclusion: Prolonged dental chair utilization during internship training significantly increased cervical pain among dental interns, while cervical mobility remained largely preserved over the short term. Early ergonomic interventions, posture education, and preventive physiotherapy strategies should be incorporated into dental curricula to reduce occupational musculoskeletal risks.
