Current Concept of Bioactive Glass-loaded 3D-Printed Alginate-based Scaffolds for Bone Tissue Engineering Applications.
Review in The archives of bone and joint surgery, 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
Bone is a mineralized connective tissue composed of osteoblasts, osteocytes, and osteoclasts, and its integrity is essential for structural and physiological function. Defects arising from trauma, tumors, or developmental abnormalities often require surgical reconstruction to restore normal performance. Autografts and allografts have long served as standard treatments for bone repair, however, their usefulness is restricted by limited availability, donor‑site complications, and the potential transmission of underlying diseases. These challenges have accelerated interest in bone tissue engineering (BTE) as an alternative strategy capable of enhancing regeneration while reducing postoperative risks. Advances in three‑dimensional (3D) printing have introduced powerful technique for fabrication of scaffolds with precisely controlled architectures and tunable mechanical and biological characteristics. This technology enables the creation of porous constructs that mimic the structural complexity of native bone, supporting cell infiltration, nutrient transport, and vascularization. Effective scaffolds for BTE must demonstrate biocompatibility, biodegradability, appropriate strength and stiffness, and the ability to promote osteogenesis and angiogenesis. Among natural polymers, alginate (Alg) has become a prominent candidate due to its inherent biocompatibility, degradability, abundance, low cost, and non‑immunogenic nature. Its versatility makes it suitable for developing customized 3D‑printed scaffolds. Additionally, bioactive glasses (BGs) are widely incorporated into composite scaffolds because their composition closely resembles the mineral phase of bone. BGs significantly enhance osteoconductivity, support mineral deposition, and can improve the mechanical resilience of polymer-based constructs. This review highlights recent progress in 3D‑printed Alg-based scaffolds for BTE, emphasizing how advanced fabrication techniques and BGs incorporation contribute to improved biological performance and structural reinforcement.
