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
objectivesThis study aimed to evaluate the clinical efficacy of pulpotomy combined with fragment reattachment in treating complicated crown-root fractures of maxillary young permanent anterior teeth.
methodsA retrospective analysis of 37 cases of complicated crown-root fractures treated at Shenzhen Children's Hospital from January 2019 to December 2023 was conducted. Outcomes such as fragment retention rate, pulp survival rate, root development, and periodontal health were assessed, and the influencing factors were analyzed.
resultsThe fragment retention rates were 80.9% at 1 year and 69.5% at 2 years. The remaining crown height (cervical half group vs. incisal half group) emerged as a critical predictor of retention (
conclusionsPulpotomy combined with fragment reattachment effectively preserves pulp vitality and restores dental function and morphology in young permanent anterior teeth. The remaining crown height serves as a key prognostic indicator for fragment retention. This approach also promotes root development and demonstrates favorable clinical outcomes.
