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
introductionEndodontic-periodontal (endo-perio) lesions are complex pathological conditions involving simultaneous pulpal and periodontal tissue destruction, posing considerable diagnostic and therapeutic challenges. Although orthodontic treatment may influence periodontal health, limited evidence exists regarding the prevalence of endo-perio lesions and their associated risk factors among orthodontic patients. This study aimed to determine the prevalence of endo-perio lesions among patients undergoing orthodontic treatment and to identify demographic, clinical, and radiographic factors associated with their occurrence. MATERIALS AND
methodsThis retrospective observational study analyzed archived records of orthodontic patients. During the six-month record-review period, 1,250 orthodontic patient records were screened. Diagnosis was established using documented clinical findings, pulp vitality testing, and radiographic evaluation. Data were then analyzed, and continuous variables were compared using the independent-samples t test or Mann-Whitney U test, whereas categorical variables were compared using the chi-square test or Fisher's exact test. Independent predictors were identified using multivariable logistic regression. Statistical significance was established at p < 0.05.
resultsThe overall prevalence of endo-perio lesions was 5.76% (72/1,250). Patients with lesions were significantly older than those without lesions (33.7 ± 9.8 vs. 28.1 ± 9.0 years; p < 0.001) and had a longer median orthodontic treatment duration (27.0 vs. 24.0 months; p = 0.009). Multivariable logistic regression identified that increasing age (adjusted OR = 1.04; 95% CI: 1.01-1.08; p = 0.012), molar teeth (adjusted OR = 2.87; 95% CI: 1.20-6.84; p = 0.017), non-vital pulp (adjusted OR = 52.90; 95% CI: 20.72-135.10; p < 0.001), deep periodontal pockets ≥5 mm (adjusted OR = 92.14; 95% CI: 21.80-389.50; p < 0.001), and radiographic bone loss (adjusted OR = 18.47; 95% CI: 5.46-62.52; p < 0.001) were independent predictors of endo-perio lesions.
conclusionOlder age, molar teeth, non-vital pulp, deep periodontal pockets, and radiographic bone loss were significant independent predictors of lesion occurrence. Comprehensive periodontal examination, pulp vitality testing, and radiographic assessment should be routinely integrated into orthodontic care to facilitate early diagnosis and interdisciplinary management.
