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: To investigate the clinical effects of regenerative endodontic procedures in the treatment of immature permanent teeth with periapical periodontitis and to analyze the factors influencing prognosis. Methods: Clinical data of 148 immature permanent teeth with periapical periodontitis treated at our hospital from January 2022 to December 2025 were retrospectively analyzed. The patients were equally divided into Group A (regenerative endodontic procedure, Results: After 6 months of therapy, Group A achieved a superior overall response rate, thicker root canal walls, longer root lengths, lower SBI, PLI, and PD, elevated gingival crevicular fluid bFGF and VEGF levels, and fewer complications ( Conclusion: Regenerative endodontic procedures are associated with favorable short-term (6-month) outcomes in immature permanent teeth with apical periodontitis, including improved root development and repair, a more favorable periodontal microenvironment, increased levels of repair-related cytokines, and fewer complications. The treatment modality and extent of the apical lesion were associated with prognosis. Individualized treatment decisions should consider the apical lesion characteristics and clinical status of the affected tooth to optimize outcomes in pediatric patients.
