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
backgroundThe purpose of the present case study is to describe the application of a modification of the Biologically-oriented Alveolar Ridge Preservation (BARP) principles in cases of peri-implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).
methodsThe technique is based on the stratification of three layers: a deep layer with a collagen sponge (CS) in the apical part of the alveolus (where the buccal bone plate was still present) to support the blood clot; a graft layer to correct the PIBD; and a superficial collagen layer to cover the graft thus providing space and enhancing clot/graft stability. Healing was obtained by primary closure.
resultsAt the re-entry procedure for implant uncovering, a complete PIBD correction with newly formed peri-implant bone up to the level of the polished collar was observed in both cases.
conclusionsThese observations suggest that BARP based on the combined use of CS and deproteinized bovine bone mineral may be regarded as a simplified treatment option to correct a PIBD at IIP. KEY POINTS: Why treat a Peri-Implant Bone Dehiscence (PIBD)? PIBD should be treated to avoid biological and esthetic complications over time. What plays a key role in this case? The stability of both the graft and the cloth is essential for providing space for bone formation to correct the PIBD; the extraction socket supports angiogenic and osteogenic properties; Primary intention closure is crucial to prevent potential infection. LIMITATION: the efficacy of the technique must be assessed. PLAIN LANGUAGE SUMMARY: This case study described the potential to correct a post-extraction osseous defect associated with a substantial portion of a dental implant which resulted exposed and without bone support on its buccal aspect. The application of a novel bone augmentation technique, namely the biologically oriented Alveolar Ridge Preservation, has been described. This simplified procedure is based on the stratification of i) a deep collagen layer in the apical part of the socket to support the blood clot and spontaneous bone formation, ii) a graft of bone substitute to correct the missing bone, and iii) a superficial collagen layer to protect the graft and the wound. After 5 months, a complete correction of the osseous defect with newly formed bone up to the head of the implant was observed in both treated cases.
