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
backgroundExtraction of mandibular third molars (MTM) is one of the most frequent surgical procedures in Oral Surgery. This intervention is not without risks, as one of the most common is an injury of the inferior alveolar nerve (IAN). The main objective of this systematic review is to compare the coronectomy technique with conventional extraction of MTM with a high risk of injury to the IAN, thus determining whether coronectomy is an effective surgical alternative in preventing nerve injuries. MATERIAL AND
methodsA bibliographical search was conducted in October 2024 in the Pub-Med and Cochrane-Database databases, and 211 studies were obtained. Finally, 16 studies were included in the systematic review, with a total sample of 2551 patients. 2280 coronectomy procedures and 841 extractions were performed.
results6.22% of the coronectomies performed were unsuccessful. The incidence of IAN injury was 6.53% in the extraction group, while in the coronectomy group, it was only 0.56%. Permanent IAN injury was 1.18% and 0.13%, respectively. The most common complication in both groups was postoperative pain, with similar results, 15.69% in the extraction group vs. 14.21% in the coronectomy group. Lingual nerve injury was infrequent and transient in both groups, affecting 0.12% of extractions and 0.26% of coronectomies. The complication with the highest incidence in the coronectomy group was root migration, mainly during the first 6 months.
conclusionsCoronectomy is a safe and effective alternative technique for the management of MTM with a high risk of IAN injury.
