Cardiopulmonary Bypass Circuit Tubing Rupture During Unplanned Conversion From Off-Pump Coronary Artery Bypass Graft Procedure: A Case Report.
Article in Cureus, 2026. 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
Cardiopulmonary bypass (CPB) is an essential component of many cardiac surgical procedures, but carries inherent risks related to its reliance on extracorporeal circulation and mechanical circuitry. Mechanical complications, though uncommon, can be rapidly life-threatening if not promptly recognized and managed. We report the case of a 68-year-old man with multivessel coronary artery disease (CAD) undergoing off-pump coronary artery bypass grafting (OPCABG) who required intraoperative conversion to CPB due to technical challenges. During the procedure, an acute rupture of the CPB circuit tubing resulted in rapid blood loss and hemodynamic instability. Immediate recognition by the anesthesia and perfusion teams allowed for prompt intervention, including circuit clamping, aggressive volume resuscitation, vasopressor support, calcium administration, and utilization of perioperative autologous cell salvage (PACS). The circuit disruption was controlled, and the patient was successfully stabilized and weaned from CPB with stable postoperative hemodynamics. This case highlights the importance of vigilance, early detection of circuit abnormalities, and coordinated multidisciplinary response in managing rare but critical CPB-related complications.
