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

Background: Stromal vascular fraction (SVF) cells and micro-fragmented adipose tissue (MFAT) have potential for treating knee osteoarthritis (OA), but their efficacy has not been compared. This study aimed to compare the clinical outcomes of SVF and MFAT for knee OA. We hypothesized that SVF provides stronger short-term effects, while MFAT offers more sustained benefits. Methods: A retrospective single-center cohort study was conducted on patients with knee OA, with 36 SVF and 36 MFAT cases selected through propensity score matching between September 2017 and February 2022. Patients with KL grades I-IV varus knee OA, significant pain (VAS ≥40), and functional impairment despite conservative treatments were included. Those with knee trauma, severe bony defects, infections, genu valgus, osteonecrosis, rheumatoid arthritis, or severe deformities were excluded. Clinical outcomes were assessed using the visual analog scale, KOOS, knee range of motion, extension/flexion strength, and MRI T2 mapping. Results: SVF and MFAT groups demonstrated significant improvements in VAS ( Conclusion: T2 mapping revealed that MFAT had better cartilage preservation than that of SVF cells in less-loaded areas, with a potentially longer-lasting therapeutic effect. These findings offer important insights for clinicians to tailor treatment strategies based on patient needs and disease progression.
