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
Iatrogenic vascular injuries are rare but potentially serious complications that can occur during orthopedic procedures involving the proximal humerus. We present a case report of a patient who sustained a brachial artery injury during a long Proximal Humeral Interlocking System (PHILOS) plating procedure for a proximal humeral fracture. A 62-year-old female patient with a left humerus proximal 1/3 shaft fracture underwent open reduction and internal fixation with a long PHILOS plate. During the procedure, difficulty was encountered in achieving adequate plate positioning due to osteoporotic bone and fracture comminution. Upon insertion of a distal second last screw, brisk brachial artery bleeding was encountered. Immediate hemostasis measures were taken, and a plastic surgeon was consulted. The brachial artery injury was identified and repaired with a cephalic vein graft harvested and flushed. Postoperatively, the patient developed median nerve neuropraxia. This case highlights the risk of iatrogenic brachial artery injury during left humerus proximal 1/3 shaft fracture fixation, especially in cases with technical challenges due to osteoporotic bone or comminution. Prompt recognition, involvement of vascular surgery, and appropriate management are crucial in mitigating potential devastating consequences. Associated neurological complications, such as nerve injuries, can also occur and should be monitored. Meticulous surgical technique, anatomical awareness, and vigilant monitoring are essential to minimize the risk of vascular and neurological complications during these procedures. Iatrogenic brachial artery injury is a rare but potentially serious complication of humerus proximal 1/3 shaft fracture. Early recognition, multidisciplinary involvement, and appropriate management strategies are crucial in optimizing patient outcomes and preventing long-term morbidity.
