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

purposeThe objective of this study was to evaluate the safety and the efficacy of intra-articular injections of autologous micro-fragmented adipose tissue in patients affected by early or moderate ankle osteoarthritis (AOA).

methodsA total of 31 symptomatic patients, aged 28-71 years, affected by AOA, were treated with 5 ml of autologous micro-fragmented adipose tissue. Clinical evaluations before the treatment and after six, 12, and 24 months were performed through American Orthopaedic Foot and Ankle Society (AOFAS) scale, the Foot and Ankle Disability Index (FADI), and Visual Analogue Scale (VAS) scores. Adverse events were recorded.

resultsNo severe complications were noted during the treatment and the follow-up period. A statistically significant improvement from basal evaluation to the six, 12-, and 24-month follow-up visit was observed, whereas a statistically significant worsening from the 12-month to the 24-month follow-up visit was showed.

conclusionThe autologous micro-fragmented adipose tissue for the treatment of pain in ankle osteoarthritis seems safe and able to provide positive clinical outcomes, potentially offering a new minimally invasive therapeutic option for patients who are not eligible for more invasive approaches. Further high-quality studies are needed to confirm these findings.
