Side-by-side versus stent-in-stent technique for stent deployment during systemic chemotherapy in biliary tract cancer patients with malignant hilar biliary obstruction.
Article in DEN open, 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
Objectives: With the improved prognosis of patients with biliary tract cancer (BTC) owing to advances in chemotherapy, long-term stent patency has become an important goal in patients undergoing biliary stent placement. We compared the duration of stent patency between unresectable BTC patients undergoing multi-stenting for malignant hilar biliary obstruction by the side-by-side (SBS) and stent-in-stent (SIS) techniques during systemic chemotherapy. Methods: We retrospectively evaluated the data of 62 unresectable BTC patients who underwent multi-stenting before the first or second cycle of first-line chemotherapy. Stent deployment was performed by the SBS technique in 40 patients (SBS group) and by the SIS technique in 22 patients (SIS group). Results: The median time-to-recurrent biliary obstruction was 147 days in the SBS group and 252 days in the SIS ( Conclusion: The duration of stent patency was shorter in the SBS group than in the SIS group; thus, the SIS technique is preferable to the SBS technique for biliary stent deployment in unresectable BTC patients during systemic chemotherapy.
