Defining tourniquetless total knee arthroplasty: A systematic review.
Review in Journal of orthopaedics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Introduction: Performing total knee arthroplasty (TKA) without the use of tourniquet is gaining popularity. However, performing a "tourniquetless TKA" has a variety of meanings regarding the timing and application of a tourniquet and associated techniques. The purpose of this systematic review was to evaluate the literature and more accurately define "tourniquetless TKA." Methods: A systematic review following PRISMA guidelines was performed of the PubMed, Web of Science, and Cochrane databases for articles published from 2016 to 2021. Inclusion criteria included papers that used "tourniquetless" or a similar term to describe their TKA procedure, original clinical studies, English language, and full-text studies. Results: A total of 1,096 studies were identified, of which 84 full text studies with 9,349 total patients were included. Overall, 17 (20.2%) of the studies performing tourniquetless TKA never applied a tourniquet, 17 (20.2%) applied a tourniquet but kept it deflated throughout the entire procedure, 2 (2.4%) applied a tourniquet and inflated during cementation only, and 48 (57.1%) did not specify. Ultimately, of the studies that did specify tourniquet use, only 17 studies (47.2%) truly never applied a tourniquet throughout the procedure. A review of 7 recommended techniques to control blood loss in tourniquetless TKA found that no one technique was performed in more than 10.6% of patients. Conclusion: Variation in the definition of tourniquetless TKA and the utilization of augmented techniques to control blood loss remains. We propose the terms "tourniquetless" for no tourniquet application, "tourniquet-available" for tourniquet applied but kept deflated throughout surgery, and "tourniquet-assisted" for tourniquet inflation during cementation only. These terms can help better differentiate the literature, guide surgeons as they transition to tourniquetless TKA, and assist in the development of more definitive protocols for tourniquetless TKA.
