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: We aimed to determine whether collagen membrane coverage in maxillary sinus floor elevation surgery, provides an advantage regarding bone regeneration. Methods: This randomized clinical trial included all healthy adults presented for dental implant placement in the posterior edentulous maxilla at the Maxillofacial Surgery Department of Mashhad Dental School, Mashhad, Iran from 2021-2022. Participants were candidates for sinus floor elevation surgery. Patients were randomly allocated to control (with membrane) and test (without membrane) groups. Surgery was performed through the lateral window technique and using allograft particles. According to the assigned study group; either a collagen membrane was placed over the osteotomy window or it was left uncovered. Six months after surgery when patients were recalled for implant placement, a bone specimen was obtained and sent for histologic and histomorphometric analysis. The predictor variable was the use of collagenous membrane and the outcome variables were the amount of newly formed bone, native bone, and connective tissue. Results: A total of 30 consecutive patients, with a mean age of 46.33±7.25 years completed the study. Histomorphometric measurements, six months after augmentation revealed that the mean area of connective tissue was significantly less in the group with membrane coverage (P=0.015). The area of newly formed bone was significantly greater in sites covered with a collagen membrane compared to grafted but uncovered sites; (P <0.001). Conclusion: Covering the lateral osteotomy window with a bioabsorbable collagenous membrane is able to significantly enhance vital bone formation and decrease connective tissue proliferation.
