Repeated intra-articular injections of umbilical cord-derived mesenchymal stem cells for knee osteoarthritis: a phase I, single-arm study.
Article in BMC musculoskeletal disorders, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
introductionStem cell therapy has emerged as an effective treatment for multiple diseases, and some studies also demonstrate that it may be a promising treatment for osteoarthritis (OA). However, few studies have clarified the safety of repeated intra-articular injection of human umbilical cord-derived mesenchymal stem cells (UC-MSCs). To promote its application in treating OA, we conducted an open-label trial to investigate the safety of repeated intra-articular injections of UC-MSCs.
methodsFourteen patients with OA (Kellgrene-Lawrence grade 2 or 3) who received repeated intra-articular injections of UC-MSCs were evaluated in three months of follow-up. The primary outcomes were the adverse events, and the second outcomes included visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scores and SF-12 quality of life score.
resultsA total of 5 of 14 patients (35.7%) experienced transient adverse reactions, which resolved spontaneously. All patients showed some improvement in knee function limitation and pain after receiving stem cell therapy. VAS score 6.0 to 3.5, WOMAC score 26.0 to 8.5, MOCART score 42.0 to 58.0, SF-12 score 39.0 to 46.0.
conclusionRepeated intra-articular injection of UC-MSCs demonstrates safety in treating OA and does not induce serious adverse events. This treatment may transiently improve symptoms in patients with knee OA and may be a potential therapeutic option for OA.
