Efficacy of Low-Dose Streptokinase Infusion in Late-Onset Permanent Tunnel Catheter Dysfunction: A Single-Center Interventional Study.
Article in Cureus, 2024. 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
Introduction Hemodialysis is a vital modality for patients with renal dysfunction, with venous access being a significant factor in its success. While arteriovenous fistulas are preferred, tunneled catheters serve as important alternatives, especially in challenging cases. Late-onset tunneled catheter dysfunction, often due to fibrin sheath formation, impedes hemodialysis efficiency. Streptokinase, a low-cost thrombolytic agent, has shown promise in resolving such complications, yet its efficacy in the Indian context remains unexplored. Methods We conducted a single-center interventional study at Mahatma Gandhi Mission (MGM) Hospital, Aurangabad, India, from May 2023 to October 2023. Ethical approval was obtained, and 10 eligible patients experiencing late-onset permanent tunnel catheter dysfunction were enrolled. Patients were treated with low-dose streptokinase, and outcomes were monitored for 60 days. Results Ten patients, evenly distributed by gender, participated, with a mean age of 48.2 ± 11.96 years. Diabetes was the predominant cause of chronic kidney disease (CKD) at 33% (3/10). All patients achieved the primary endpoint of blood flow rate (BFR) >300 ml/min post-streptokinase treatment, with an overall success rate of 100%. Group A had the highest average gain in catheter days (80.6 ± 7.59), followed by Group B (64 ± 1), while Group C showed variations in catheter days between the first (26.2 ± 6.8) and second insertion (32.5 ± 1.76). Eight patients maintained catheter patency during the 60-day follow-up. Adverse effects, primarily minor, were observed. The dosage rationale involved an eight-hour infusion at 4,000 units per hour. Conclusion Streptokinase emerges as cost-effective and efficacious for maintaining the patency of late-onset tunnel catheter dysfunction in resource-limited settings, particularly in younger patients. Caution is advised for older individuals with prolonged CKD.
