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: Atrophic acne scars represent a therapeutic challenge with significant psychosocial impact. Autologous cell-based therapies, such as stromal vascular fraction (SVF) and the ReCell® system, aim to address the underlying dermal matrix deficiency through regenerative mechanisms. This systematic review and meta-analysis provides an updated and comprehensive quantitative synthesis of their standalone efficacy and safety. Methods: We conducted a systematic search of multiple databases (PubMed, Embase, Cochrane Library, CNKI, Wanfang) from inception to December 2025 for randomized controlled trials (RCTs) and split-face studies comparing autologous cell therapies (SVF, ReCell, fat grafting) with control treatments (e.g., saline, laser alone) for atrophic acne scars. The primary outcome was the change in the ECCA grading score. Secondary outcomes included patient satisfaction, objective scar metrics, healing time, and adverse events. Data were pooled using random-effects models. Results: Eighteen studies involving 500 participants were included. Autologous cell therapies significantly reduced ECCA scores compared to controls (Standardized Mean Difference [SMD] = -1.25, 95% CI: -1.80 to -0.70, p < 0.001; I Conclusion: Autologous cell-based therapies, particularly SVF, are effective and safe for improving atrophic acne scars, offering superior clinical, patient-reported, and safety outcomes compared to standard controls. The integration of detailed methodological insights provides a valuable evidence base to guide clinical protocol optimization and future research focused on standardization and long-term efficacy.
