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.
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
backgroundDisc displacement (DD) is among the most prevalent intra-articular temporomandibular disorders. Identifying associated factors can support early diagnosis and management. The objective of this study was to evaluate the relationship between disc conditions and patient demographics and clinical characteristics.
methodsThis retrospective study analyzed 770 patient records collected from 2021 to 2025 using data extracted from the hospital's digital system. Variables included demographic information, behavioral habits, occlusal characteristics, clinical findings, and temporomandibular joint (TMJ) diagnoses. Statistical analyses were performed using descriptive statistics, chi-square tests, independent
resultsDD was diagnosed with 420 patients (54.5%). DD patients were significantly younger (mean 39.0 years,
conclusionsDD was associated with demographic and behavioral factors, particularly younger age, female sex, and certain oral habits. Functional occlusal contacts were also found to be associated with an increased likelihood of DD. Comprehensive assessment is essential for diagnosis and management.
