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: Protein A immunoadsorption (IA) is proving to be an effective treatment method for autoimmune diseases and other disorders. Regional citrate anticoagulation (RCA) prevents clotting in extracorporeal circuits without increasing hemorrhage risk in high bleeding risk patients, but there are no specific guidelines for its application in IA. We aimed to evaluate the safety and adverse effects of RCA used in IA therapy. Methods: We conducted a retrospective cohort study of forty-five RCA-IA sessions in 14 HLA-incompatible kidney transplant recipients with focus on the safety and adverse effects of RCA in IA. The extracorporeal circuit was equipped with 4% trisodium citrate solution as an anticoagulant and 10% calcium gluconate solution to compensate for calcium loss. The adverse events, including coagulation and blood biochemical indexes, especially calcium level, were recorded. Results: Our study found that 93.33% of the sessions were without circuit clotting or other significant complications. A slight decrease in fibrinogen level was observed, but without significant variations in other coagulation indexes or platelet count. There was a slight elevation in the potential of hydrogen, bicarbonate, and base excess after 2 h and 6 h posttreatment relative to prior treatment, but these returned to normal levels within 24 h posttreatment. Conclusion: RCA is a feasible, effective, and safe anticoagulation option for IA treatment in HLA-incompatible kidney transplant recipients. Electrolyte disturbances, especially alkalosis, hypocalcemia, hypomagnesemia, and fluid status, should be closely monitored and managed.
