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

backgroundChronic lower extremity ulcers (CLEUs) remain a major clinical challenge due to their prolonged healing process and risk of amputation. Stem cell therapy (SCT) has emerged as a promising regenerative strategy, with various cell types being explored for their efficacy in treating CLEUs. This umbrella review aims to consolidate the existing evidence on stem cell interventions for CLEUs, providing a comprehensive overview of the current research landscape.

methodsThis umbrella review was conducted following the PRIOR and PRISMA guidelines. We searched across PubMed, Embase, Web of Science, and Cochrane Library databases for systematic reviews (SRs) and meta-analyses (MAs) that included randomized controlled trials (RCTs) on SCT for CLEUs. The methodological quality and evidence quality of the SRs/MAs were assessed by AMSTAR 2 and GRADE. A quantitative synthesis of all RCTs included in the SRs/MAs to obtain objective and updated conclusions.

resultsA total of 28 SRs/MAs involving 72 RCTs were included. Our updated meta-analysis reinforces that SCT offers potential therapeutic benefits for CLEUs, including improved healing rates, amelioration of tissue perfusion and pain-related indicators, and more favorable prognostic outcomes. No significant difference in all-cause mortality was observed between the SCT and control groups.

conclusionSCT represents a promising adjunctive therapy for CLEUs, with many studies demonstrating its safety and potential benefits. Since current evidence is limited by methodological flaws and study heterogeneity, high-quality RCTs in the future are crucial to prove the benefits of SCT for CLEUs truly.
