In vitro evaluation of anticoagulant therapy management when urgent percutaneous coronary intervention is required in rivaroxaban-treated patients.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05541757 (In-Vitro Evaluation of Anticoagulant Therapy Management When Urgent Percutaneous Coronary Intervention is Required in Rivaroxaban-Treated Patients), which is not on this map.

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.

Abstract
We investigated in vitro the management of intraprocedural anticoagulation in patients requiring immediate percutaneous coronary intervention (PCI) while using regular direct oral anticoagulants (DOACs). Twenty-five patients taking 20 mg of rivaroxaban once daily comprised the study group, while five healthy volunteers included the control group. In the study group, a beginning (24 h after the last rivaroxaban dose) examination was performed. Then, the effects of basal and four different anticoagulant doses (50 IU/kg unfractionated heparin (UFH), 100 IU/kg UFH, 0.5 mg/kg enoxaparin, and 1 mg/kg enoxaparin) on coagulation parameters were investigated at the 4th and 12th h following rivaroxaban intake. The effects of four different anticoagulant doses were evaluated in the control group. The anticoagulant activity was assessed mainly by anti-factor Xa (anti-Xa) levels. Beginning anti-Xa levels were significantly higher in the study group than in the control group (0.69 ± 0.77 IU/mL vs. 0.20 ± 0.14 IU/mL; p < 0.05). The study group's 4th and 12th-h anti-Xa levels were significantly higher than the beginning level (1.96 ± 1.35 IU/mL vs. 0.69 ± 0.77 IU/mL; p < 0.001 and 0.94 ± 1.21 IU/mL vs. 0.69 ± 0.77 IU/mL; p < 0.05, respectively). Anti-Xa levels increased significantly in the study group with the addition of UFH and enoxaparin doses at the 4th and 12th h than the beginning (p < 0.001 at all doses). The safest anti-Xa level (from 0.94 ± 1.21 to 2.00 ± 1.02 IU/mL) was achieved 12 h after rivaroxaban with 0.5 mg/kg enoxaparin. Anticoagulant activity was sufficient for urgent PCI at the 4th h after rivaroxaban treatment, and additional anticoagulant administration may not be required at this time. Twelve hours after taking rivaroxaban, administering 0.5 mg/kg of enoxaparin may provide adequate and safe anticoagulant activity for immediate PCI. This experimental study result should confirm with clinical trials (NCT05541757).
