Fixed-Dose Four-Factor Prothrombin Complex Concentrate for Reversal of Anticoagulation: Evaluation of Efficacy, Safety, and Cost Savings.

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
Background: Four-factor prothrombin complex concentrate (4F-PCC) is used for warfarin reversal and off-label management of bleeding in patients taking direct oral anticoagulants (DOACs). Dosing strategies that optimize hemostatic efficacy and cost, such as fixed dosing of 4F-PCC, are still under evaluation. The objective of this study was to retrospectively evaluate the efficacy, safety, and cost savings of fixed-dosing of 4F-PCC (1,500 IU for warfarin, 2,000 IU for DOACs). Methods: Patients records from October 1, 2018, to April 30, 2021, at three hospitals within the Froedtert Health System were retrospectively reviewed for individuals who received fixed-dosing of 4F-PCC. Safety and efficacy were reflected in 30-day bleeding and thrombosis events, the need for repeat doses, and all-cause mortality. Cost savings were defined as the difference in the cost between the administration of fixed-dosing and the projected weight- and international normalized ratio (INR)-based dosing based on the package insert for warfarin reversal or 50 IU/kg in patients treated with DOACs. Results: A total of 592 patients received fixed-dosing of 4F-PCC during the prespecified period, of whom 541 received it for warfarin reversal (n = 414) or DOACs (n = 127) management in emergency settings. INR below 2 was achieved in 89% of patients on warfarin. Less than 5% in either group required repeat doses of 4F-PCC. Within 30 days, both groups had similar bleeding (12%) and thrombotic (5%) events. All-cause 30-day mortality rates in patients treated with warfarin and DOACs were 24% and 30%, respectively. The median cost savings of fixed-dosing per patient on warfarin and DOACs were $1,567 and $3,936, respectively, with annualized median hospital cost savings of $176,239 and $146,733, respectively. Conclusions: Fixed-dosing of 4F-PCC had significantly less cost than adjusted dose and is associated with similar rates of thrombosis and death compared to other studies.
