Hyaluronic acid-alendronate conjugate: A macromolecular drug delivery system for intra-articular treatment of osteoarthritis.
Article in Osteoarthritis and cartilage open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Objective: Osteoarthritis (OA) is a painful degenerative disease of the whole joint structure, including articular cartilage, synovial fluid, and subchondral bone. Hyaluronic acid (HA), an anionic non-sulfated glycosaminoglycan, is commonly used for intra-articular (IA) treatment in OA, while bisphosphonates (BPs) are anti-resorptive drugs that act on the bone. Here, a novel conjugate with a covalent and hydrolysable linker between HA and alendronate (ALD) was designed as an attractive therapeutic strategy for IA drug delivery. Design: The HA-ALD derivative was synthesized and tested in comparison with a simple mixture of HA and ALD for Results: The structure of HA-ALD was elucidated exhibiting no depolymerization and efficient drug incorporation. The controlled ALD release Conclusion: This new HA-ALD derivative opens the door to a new approach for OA treatment, as it combines viscosupplementation and biological effects of HA with the pharmacological activity of BPs. Prolonged ALD release increased rheological properties and beneficial effect against cartilage degradation make it a promising IA therapy for OA.
