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

objectivesTo evaluate the prevalence of degenerative bony changes of the mandibular condyle and their associations with age, gender, and joint laterality. MATERIALS AND

methodsCBCT scans of 112 temporomandibular joints of 56 clinically symptomatic patients were included based on predefined inclusion and exclusion criteria. Degenerative changes, including erosion, flattening, osteophytes, subchondral sclerosis, and subcortical pseudocysts, were assessed for their presence, frequency, and demographic associations using the Chi-square test, McNemar test, Spearman's correlation analysis, and Cohen's kappa statistics.

resultsErosion was the most prevalent finding (84.8%) and frequently coexisted with flattening. Subcortical pseudocyst showed a positive association with increasing age (p < 0.05), osteophytes were more commonly observed in males (p < 0.01), and subchondral sclerosis occurred more frequently on the left side (p < 0.05).

conclusionSymptomatic TMJs demonstrated at least one degenerative change, where Erosion was the most prevalent, and subcortical pseudocyst was the least common degenerative change in the mandibular condyle. Age, gender, and joint side showed associations with specific changes.
