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
BACKGROUND Pheochromocytoma is a rare neuroendocrine tumor. Some patients are asymptomatic, and misdiagnosis is common, especially when it lacks typical imaging features. In asymptomatic patients misdiagnosed with pheochromocytoma, hemodynamic instability often occurs during surgical procedures, posing significant challenges to surgeons and anesthesiologists. This case report presents a patient who was misdiagnosed as having a pancreatic cystadenoma prior to surgery, aiming to explore the intraoperative decision-making and considerations for such cases. CASE REPORT A 48-year-old woman with abdominal pain was preoperatively diagnosed with pancreatic cystadenoma by imaging. Laparoscopic surgery was performed following standard procedures, including patient positioning, stomach suspension, tumor search, and tissue dissection. The surgery lasted 156 min, with minimal blood loss (50 mL). Intraoperative hemodynamic instability occurred, and the final histopathological report confirmed the tumor as a pheochromocytoma. The patient was monitored in the intensive care unit (ICU) after surgery and was discharged on the 8th postoperative day, without complications. CONCLUSIONS Clinicians should be aware of the limitations of imaging. When dealing with abdominal tumors lacking typical features, especially those located in the adrenal gland or para-adrenal region, a high suspicion for asymptomatic pheochromocytoma is necessary. In the event of intraoperative hemodynamic instability, a high degree of suspicion for pheochromocytoma is needed. Moreover, it is crucial to strengthen multidisciplinary collaboration and emphasize the optimization of preoperative laboratory tests and examinations to compensate for the limitations of imaging studies. Surgeons need to be prepared for unexpected findings during surgery and adjust the surgical plan according to local anatomy to improve surgical safety and success rates.
