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
Knee osteoarthritis (KOA) is a degenerative joint condition characterized by progressive cartilage deterioration and chronic pain, leading to functional impairment. Bone marrow-derived orthobiologics, such as bone marrow aspirate clot (BMA-clot) and bone marrow aspirate concentrate (BMAC), have emerged as promising regenerative therapies. Despite their growing clinical use, no randomized clinical trials to date have directly compared the efficacy and safety of these two approaches in patients with KOA, leaving a gap in the current evidence base. This study aimed to compare the efficacy and safety of intra-articularBMA-clot and BMAC in patients with moderate to severe KOA over a 12-month follow-up period. In this prospective, randomized, double-blind clinical trial, patients aged 50-80 years with Kellgren-Lawrence grade 3-4 KOA were enrolled. Participants received thr ee monthly intra-articular injections of eitherBMA-clot or BMAC. The primary outcome was functional improvement assessed by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Secondary outcomes included pain reduction (Visual Analog Scale) and quality of life (Short Form-36, SF-36). Adverse events were monitored, and data were analysed using mixed-effectsmodels. Both treatments resulted in significant improvements in pain, function, and quality of life throughout the 12-month period. Clinical outcomes between the BMA-clot and BMAC groups were not statistically different. The incidence of adverse events was low, with no serious complications observed. Intra-articular administration of BMA-clot and BMAC appears to be safe and effective for the management of moderate to severe KOA, providing sustained symptom relief and functional gains over a 12-month period. Given its simpler preparation and lower cost, BMA-clot may represent a more accessible therapeutic option in clinical settings.
