Self-expandable metal vs. plastic stents for preoperative biliary drainage in patients receiving neoadjuvant chemotherapy.
Review in Clinical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Neoadjuvant chemotherapy (NAC) improves the rate of curative resection and overall prognosis in patients with resectable or borderline resectable pancreatic cancer. The treatment period from the initiation of NAC to surgery typically ranges from 2 to 6 months. In cases of malignant biliary obstruction caused by pancreatic cancer, maintaining preoperative biliary drainage (PBD) until surgery is essential to continue NAC. Minimizing adverse events related to endoscopic biliary drainage and avoiding perioperative adverse events are crucial. Plastic stents (PSs) are commonly used for PBD; however, the extended duration of PBD required for NAC increases the risk of recurrent biliary obstruction (RBO), potentially leading to discontinuation of NAC. Therefore, preventing RBO during PBD in patients with pancreatic cancer receiving NAC is important. The placement of self-expandable metal stents (SEMSs) for PBD significantly reduces the rate of RBO compared with PS placement. Although SEMS placement may increase the risk of pancreatitis or cholecystitis, its effect on postoperative outcomes is comparable to that of PS placement. Given their lower rate of RBO, SEMSs are considered more suitable than PSs for PBD in patients with pancreatic cancer receiving NAC.
