One Dose Versus Two Doses of Intravenous Tranexamic Acid in Revision Total Joint Arthroplasty.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTranexamic acid (TXA) is often used to reduce the amount of blood lost during total joint arthroplasty (TJA) and decrease the incidence of postoperative transfusion. Despite its extensive use, the ideal dosing regimen is still widely debated. The primary aims of this study were to compare single-dose and two-dose regimens on postoperative hemoglobin levels, transfusion rates, and 30-day complication rates in patients who underwent revision TJA.
methodsThis retrospective study included patients who underwent revision total knee arthroplasty or revision total hip arthroplasty between April 2014 and November 2020 at a single academic institution. Patients were divided into two groups: One group received a 1 g bolus of intravenous TXA just before incision and another intravenous 1 g bolus during wound closure (n = 151), and the second group received a single, 1-g, intravenous bolus of TXA just before incision (n = 189).
resultsNo notable statistical differences were found between the two cohorts when evaluating postoperative hemoglobin levels (b = -0.18, 95% confidence interval [CI]: -0.39 to 0.03; P = 0.09), transfusion rates (odds ratio [OR] = 0.74, 95% CI: 0.39 to 1.38; P = 0.34), length of hospital stay (rate ratio = 0.95, 95% CI: 0.84 to 1.08; P = 0.43), and 30-day postoperative complication rates (OR = 1.30, 95% CI: 0.54 to 3.15; P = 0.56) even after controlling for patient characteristics and surgical factors.
conclusionIn this study, no association was found between a single dose of perioperative TXA during revision TJA and increased rates of post-operative complications when compared with two-doses, suggesting comparable efficacy.
