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: Patient Blood Management (PBM) has become an essential component of contemporary perioperative medicine. Major orthopedic surgery has historically been associated with substantial perioperative blood loss and high allogeneic transfusion rates. The aim of this study was to describe the temporal association between the progressive implementation of a multidisciplinary PBM programme and transfusion rates in major orthopedic surgery at our institution. Materials and methods: This retrospective observational single-centre study on annual institutional aggregated data included patients undergoing major orthopedic procedures, including total hip arthroplasty (THA), total knee arthroplasty (TKA), and major spine surgery (MSS), between 2012 and 2018. The PBM programme incorporated a multidisciplinary perioperative approach consisting of preoperative anemia management, restrictive transfusion thresholds, a single-unit transfusion policy, routine tranexamic acid (TXA) administration, meticulous surgical hemostasis, minimally invasive surgical techniques, and selective use of intraoperative cell salvage systems. Annual transfusion rates and PBM-related interventions were analysed over the study period for the overall cohort and separately for each procedure group. Results: A total of 7,439 major orthopedic procedures were analysed. Overall transfusion rates decreased from 38.1% in 2012 to 9.2% in 2018, corresponding to an absolute reduction of 28.9% and a relative reduction of 76.0%. Similar reductions were observed for THA (45.0% to 13.6%), TKA (31.7% to 4.6%), and MSS (32.1% to 9.1%). Logistic regression demonstrated that each additional calendar year was associated with a significant reduction in the odds of transfusion in the overall cohort (OR 0.72, 95% CI 0.70-0.74; Conclusion: The present study demonstrates that multidisciplinary PBM implementation substantially reduces transfusion requirements in major orthopedic surgery. PBM should not be regarded as a single intervention, but rather as a coordinated perioperative strategy based on synergistic implementation of multiple blood conservation measures, resulting in improved perioperative management.
