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
backgroundVertically fractured teeth often have a poor prognosis, and extraction is considered the most predictable treatment. Conventional management has consisted of preservation therapy involving extraction, bonding, root restoration, and replantation of fractured teeth. However, these methods fail to adequately address the periodontal tissue damage associated with root fractures. This report describes successful periodontal tissue regeneration using basic fibroblast growth factor (FGF-2) combined with a carbonate apatite-based bone graft material (CaAp) as a scaffold during the replantation of vertically fractured teeth.
methodsOur series included four patients: a 57-year-old woman, a 59-year-old woman, a 45-year-old man, and a 41-year-old woman, all diagnosed with vertically fractured teeth. The fractured teeth were extracted, bonded using 4-methacryloxyethyl trimellitate anhydride in methyl methacrylate initiated by tri-n-butyl borane (4-META/MMA-TBB) resin, and replanted. CaAp was applied to the extraction sockets; FGF-2 was administered to the periodontal ligament-deficient root areas prior to replantation.
resultsIn all cases, periodontal pocket depths were reduced to 3 mm or less, and no signs of inflammation were evident. Cone-beam computed tomography revealed substantial regeneration of periodontal tissues.
conclusionsThe combination of FGF-2 and CaAp during the replantation of vertically fractured teeth promotes periodontal tissue regeneration and demonstrates potential for long-term tooth preservation. KEY POINTS: What new information do these cases provide? This is the first report to our knowledge demonstrating that replantation of a root-fractured tooth, historically considered suitable only for extraction, can achieve substantial periodontal tissue regeneration. This regeneration was accomplished by bonding and restoring the tooth using 4-methacryloxyethyl trimellitate anhydride in methyl methacrylate initiated by tri-n-butyl borane (4-META/MMA-TBB) resin in combination with fibroblast growth factor (FGF-2) and carbonate apatite-based bone graft material (CaAp). What are the keys to successful management of these cases? Atraumatic tooth extraction Thorough curettage of the extraction socket Comprehensive debridement of the fractured root surface Precise bonding and restoration of the fractured tooth Effective application of FGF-2 and CaAp, with accurate positioning and stabilization of the replanted tooth What are the primary limitations to success in these cases? The mechanical factors that can cause root fracture need to be eliminated for this treatment to succeed. The long-term prognosis depends on consistent follow-up and monitoring. The procedure is highly technique-sensitive; outcomes are closely associated with operator skill and experience.
