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

backgroundThis study aimed to enhance understanding of how unilateral posterior tooth loss (UPTL) affects temporomandibular joint (TMJ) structures and to explore potential influencing factors on joint morphology.

methodsThe study included 68 subjects (34 patients with UPTL and 34 with complete dentition), divided into the missing group (n = 34 joint sides), the contralateral group (n = 34 joint sides), and the control group (n = 68 joint sides). Morphological measurement of the condyle, glenoid fossa and joint spaces were performed using cone-beam computed tomography (CBCT) and Mimics software. Analyses and comparisons were made among the three groups, with subgroup analyses based on the duration of tooth loss (< 1 year and ≥ 1 year), first molar loss, and the presence of unilateral chewing habit (UCH).

resultsSome significant differences among the control, the missing, and the contralateral groups were observed in measurements of the glenoid fossa and joint spaces (P < 0.05). When tooth loss lasted less than 1 year, the contralateral side exhibited significantly larger posterior joint spaces than the missing side (P < 0.05), whereas no differences were observed at ≥ 1 year. In the first molar loss subgroup, the anteroposterior and mediolateral diameters of the glenoid fossa were significantly larger on the contralateral side than on the missing side (P < 0.05). Moreover, unilateral chewers with UPTL exhibited significantly smaller anteroposterior condylar diameters on the preferred chewing side (P < 0.01).

conclusionAn overall enlargement of both the glenoid fossa and joint spaces was observed in patients following UPTL; the glenoid fossa was found to be more susceptible to bone resorption than the condyle. Factors such as the duration of tooth loss, the absence of the first molar, and UCH contribute variably to these structural changes, indicating that different tooth-loss conditions can impose distinct biomechanical impacts on the TMJ.
