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
Objective: This study retrospectively analyzes two mandibular resection techniques for T3-stage lower gingival carcinoma, aiming to compare their impact on patient prognosis. Methods: Retrospective cohort study. Data from 78 cases of T3-stage lower gingival carcinoma involving the mandible were reviewed in our Department of Head and Neck Surgery. These cases included patients who underwent either marginal mandibulectomy or segmental mandibulectomy. A cohort analysis was performed to evaluate the clinical outcomes and identify factors influencing prognosis in T3-stage lower gingival carcinoma. Results: Thirty-eight patients underwent marginal mandibulectomy, while 40 underwent segmental mandibulectomy. The 3-year overall survival (OS) rate in the marginal mandibulectomy group was 70.8%, with a 5-year OS rate of 52.1%. In the segmental mandibulectomy group, the 3-year OS was 68.1%, and the 5-year OS rate was 52.7%, with no statistically significant difference between the two groups ( Conclusion: The marginal mandibulectomy has been proven to be an oncologically safe method with satisfactory mandibular functional outcomes in selected cases of T3-stage lower gingival carcinoma.
