In Vitro Evaluation of an Adhesive Hydrogel-Based Chondrocyte Carrier for Enhanced Therapeutic Delivery.
Article in Macromolecular bioscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Large knee chondral defects remain a major challenge in orthopaedic surgery and may lead to osteoarthritis. Autologous chondrocyte implantation (ACI) is a widely used regenerative therapy; current techniques have inherent limitations related to cell delivery, retention, and integration. This study investigates a novel adhesive hydrogel as a cell carrier for enhanced therapeutic delivery in cartilage repair. This injectable hydrogel can lead to a paradigm shift in ACI through removing the need for membranes entirely and enabling direct in situ fixation of cell-laden constructs while preserving the chondrocytic phenotype. In this work, we report in vitro encapsulation of human autologous chondrocytes (HACs) using cells from five orthopedic patients within this hydrogel with subsequent in vitro evaluation of functional outcomes, including cell viability, glycosaminoglycan production, histological and immunohistological outcomes, and evolution of mechanical properties of the cell constructs. Moreover, by analyzing the hydrogel polymer content (PC), we identified an optimal formulation balancing biological activity and mechanical integrity.
