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 (TMD) aetiological factors have multidimensional, biomechanical, neuromuscular, biopsychosocial and neurobiological aspects. The relationship between work environment factors or occupational stress and TMD is not sufficiently investigated and is still poorly understood.

objectiveTo investigate work-related stress and the effect of personal computer (PC) use on TMD.

methodsA questionnaire-based survey that was conducted among 5619 employees of three companies. The questionnaire was used to screen TMD-related symptoms (TRS), habitual behaviours, psychosocial status, awake and sleep bruxism and time spent using a PC at work. After excluding missing data values, 4776 individuals were included in the analysis. Structural equation modelling (SEM) was used to test the hypothesised models that correlated TRS with the other factors of the questionnaire, and to examine the effect of the time spent using the PC on men and women in our sample. Statistical significance was set at p < 0.05.

resultsSEM revealed that psychosocial factors affected TRS indirectly through their direct effect on sleep bruxism and other behavioural factors which had a direct effect on TRS. The effect of PC usage time was greater for women than for men.

conclusionsBehavioural factors, including SB, may have a direct effect on TRS, while psychosocial factors may have an indirect effect on TRS. In addition, the results suggest that prolonged PC use influences behavioural and psychosocial factors, and this was especially true for women.
