1 · What the graph read from it

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.

2 · The registry

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

Introduction: This study aimed to determine the association between the baseline magnetic resonance imaging (MRI) findings and clinical outcomes after articular injection of adipose-derived mesenchymal stem cells (ASCs) for knee osteoarthritis (KOA). Methods: This retrospective study included 149 patients with varus-type KOA treated with a single intraarticular ASC injection. All patients underwent a MRI evaluation before treatment. Patients were categorized following the MRI Osteoarthritis Knee Score (MOAKS) system cartilage score into the mild, moderate, or severe KOA groups. Additionally, joint effusion and synovitis, bone marrow lesions (BMLs), and meniscal extrusions were graded with the MOAKS. Knee Osteoarthritis Outcome Score (KOOS) was obtained at baseline, 1-, 3-, 6-, and 12-month posttreatment. The responder rate in the Outcome Measures in Arthritis Clinical Trials-Osteoarthritis Research Society International was assessed with the KOOS. Multivariate logistic regression analyses were conducted to determine factors associated with the responder rate. Results: All KOOS subscales significantly enhanced with the greatest improvement from baseline to 6 months which plateaued between 6 and 12 months. The responder rate was 65.4 % in the mild/moderate KOA compared to 35.2 % in the severe KOA at 12 months. Lower OA grade (odds ratio [OR]: 0.52; 95 % confidence interval (CI): 0.31-0.88; Conclusions: ASC treatment for KOA enhanced short-term clinical outcomes. MRI findings, including cartilage lesions, BMLs, and meniscal extrusion, were associated with responder rate, helping physicians identify which patients may benefit from this therapy.
