Keller Funnel Efficacy in "No Touch" Breast Augmentation and Reconstruction: A Systematic Review.
Article in Plastic and reconstructive surgery. Global open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 1 of them a synthesis that pooled 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.
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
Breast augmentation is one of the most common aesthetic surgical procedures. Tissue expansion followed by permanent implants is the most frequent postmastectomy breast reconstruction method. Implant contamination remains a critical problem with these procedures' resulting in acute infection as well as capsular contracture. To reduce the risk of implant contamination, the "no-touch technique" utilizing the Keller funnel has been adopted by many surgeons. This systematic review aims to investigate the advantages of the Keller funnel method for breast augmentation-reconstruction. Methods: A systematic review of PubMed, Embase, the Cochrane database, and Google Scholar was performed between 2005 and 2021. All clinical-based, retrospective and prospective studies utilizing the Keller funnel method for breast implant insertion were selected. Results: Six studies were identified for evaluation: five were retrospective cohorts and one was a prospective trial. No randomized controlled trials were found. Outcomes reported included lower rates of capsular contracture (RR, 0.42; Conclusions: This review suggests that the Keller funnel is a useful method for no-touch breast augmentation and reconstruction surgery. The Keller funnel reduces subsequent capsular contracture rate, surgical time, and incision length and allows for easier insertion. However, our findings support recommendation of a prospective randomized controlled clinical trial with larger population size and follow-up intervals.
