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
Background: Dentists frequently conduct tooth extractions when there is damage to the tooth or the tissue that supports it. When a tooth is extracted, the alveolar bone will sustain injury. Most of the initial bone volume is lost following the healing phase after extraction. Rehabilitation must start as soon as a tooth is missing, mainly because the alveolar bone is severely damaged during the tooth extraction, particularly in the buccal region where the tooth is removed. Dental implant is one method of replacing lost teeth. One of the most important elements influencing the clinical result of dental implants is a change in the dimension of the alveolar bone. Several bone-grafting techniques, such as socket preservation techniques, have been developed to increase the volume of bone throughout the healing phase after tooth extraction. This study aims to assess the impact rhBMP-2 on creating bone regeneration through VEGF and HIF-1α in the mandibular socket post-extraction in Wistar rats. Method: On the anterior side of the mandible, in the socket area where the tooth was extracted, rhBMP-2 was injected into the socket, and the xenograft material was applied with a syringe. Male, 9-week-old Wistar rats were chosen (n = 30). Result: Our statistical evaluations have revealed a significantly higher VEGF-A and HIF-1α expression post-extraction of the rhBMP-2 and xenograft group compared to other group treatments. These findings are significant as they provide a deeper understanding of the mechanisms involved in bone regeneration post-extraction. Conclusion: Our study suggests that injecting rhBMP-2 into the grafted material and socket extraction during GBR dramatically increases the expression of VEGF-A and HIF-1α. These findings have the potential to significantly impact oral surgery and regenerative dentistry, opening up new possibilities for enhancing bone regeneration techniques.
