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
objectiveTo address the mismatch between the support center and the occlusal load center in implant-supported overdentures, this study proposed a novel centralized occlusal scheme. This design aimed to utilize the supportive capacity of the anterior mandibular implants and the maxillary canine pillars by establishing occlusal contacts in the canine region. A preliminary evaluation of the clinical feasibility of this new occlusal scheme was conducted.
methodsIn this study, five completely edentulous patients received two implants in the mandible. Each participant was provided with two complete prosthetic sets: mandibular implant-supported overdentures and corresponding complete maxillary dentures featuring either a conventional bilateral balanced occlusion or the novel centralized occlusal scheme, delivered in a randomized crossover sequence. For the new scheme, the maxillary canines were reshaped referencing the premolars, while preserving their labial contour and occlusal balance, the lingual fossa was modified to establish centric occlusal contacts. A comprehensive evaluation was conducted using standardized methods: chewing efficiency was measured using the two-color chewing gum method, occlusal contact area was calculated digitally using virtual articulating paper method, and patient satisfaction was assessed using validated questionnaires, and stress distribution patterns were examined through detailed three-dimensional finite element analysis.
resultsCompared with the conventional occlusal scheme, the centralized occlusal scheme achieved
conclusionThe proposed novel centralized occlusal scheme can enhance occlusal contact area and chewing efficiency by utilizing the support capacity of the anterior mandibular implants and the maxillary canine pillars, while maintaining denture stability, balance, aesthetics, and patient satisfaction. This study provides a new approach and preliminary evidence for improving the occlusal design of implant-supported overdentures.
