Safety and Efficacy of a Small J-Tipped Guidewire for Pancreatic Duct Endoscopic Intervention.
Observational study in Canadian journal of gastroenterology & hepatology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background and Aims: The insertion of the guidewires (GWs) into the pancreatic duct is technically difficult, and there is a risk of post-ERCP pancreatitis (PEP). The aim of this study was to evaluate the safety and efficacy of a small J-tipped guidewire for pancreatic duct endoscopic intervention. Methods: This single-site retrospective study was conducted to assess the procedural success rate and adverse events of endoscopic transpapillary interventions to the pancreatic duct in 114 cases using the small J-tipped GW and 180 cases using the angle-tipped GW. Results: The procedural success rate was significantly higher in the small J-tipped GW group compared with that in the angle-tipped GW group (76% versus 47%, P < 0.001). The procedural success-related factors were chronic pancreatitis (OR 0.43, 95% CI 0.22-0.82, P = 0.01), flexion angle of the pancreatic duct < 90° (OR 0.50, 95% CI 0.30-0.80, P = 0.01), and use of the small J-tipped GW (OR 4.63, 95% CI 2.61-8.20, P < 0.001). The rates of total post-ERCP pancreatitis were significantly lower in the small J-tipped GW group compared with that in the angle-tipped GW group (3.5% versus 12.2%, P = 0.01). Multivariate analysis of pancreatitis risk factors indicated that only the use of the small J-tipped GW was a factor in decreasing the risk of developing pancreatitis (OR 0.12, 95% CI 0.09-0.85, P = 0.02). Conclusions: Small J-tipped GWs increase the success rate of the pancreatic duct endoscopic intervention as well as a reduced risk of developing postoperative pancreatitis.
