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

backgroundTemporomandibular disorders (TMDs) rank as the third most prevalent condition in dental clinical practice, with a notably high incidence among college students. Psychological stress has been implicated as a potential risk factor. This study examines the prevalence, clinical characteristics, and risk factors of TMDs in medical and dental students, a population subject to elevated stress levels.

methodsA cross-sectional, anonymized web-based survey was administered to medical and dental students at Fujian Medical University in China. The research collected and analyzed demographic and temporomandibular disorders (TMDs) characteristics, employing logistic regression to identify significant risk factors contributing to TMDs prevalence.

resultsA total of 1,223 students responded to the survey, with a response rate of 82.7%, including 732 medical students and 491 dental students. The overall prevalence of self-reported TMD symptoms was 49.7% for total students. However, among different symptoms of TMDs, only 'jaw joint noises' prevalence differed between medical (26.9%) and dental (33.2%) students (P = 0.02). Dental students showed higher TMD knowledge and more regular dental check-ups (P < 0.001). Furthermore, the prevalence of headaches varied among clinical medical and dental students based on academic grades (P = 0.04 and P = 0.007, respectively). Risk factors for TMDs included a higher Perceived Stress Scale (PSS)-10 score (P < 0.001), longer sitting time (P = 0.039), and fewer dental visits (P = 0.033).

conclusionsHigh TMD prevalence exists among Chinese medical and dental students. Risk factors include high-stress levels, prolonged sitting, and infrequent dental visits. Anxiety and depression are strongly associated with TMDs.
