1 · What the graph read from it

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.

2 · The registry

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

backgroundThrough-the-scope implantation of self-expandable metal stents can be used for the palliation of malignant gastric outlet obstruction. Although covered stents were developed to prevent tumor ingrowth, often seen with uncovered stents, migration is still a major problem. Especially, surgical treatment is required for some patients if distal migration occurs.

aimsTo evaluate the usefulness of the newly designed winged stent that was developed to prevent distal stent migration.

methodsThis was a single-center, single-arm, retrospective study. A total of 63 inoperable cancer patients with symptomatic gastric outlet obstruction were reviewed to evaluate the safety and efficacy of a newly designed partially covered self-expandable metal stent with star-shaped wing flaps at the proximal end to reduce distal stent migration.

resultsTechnical and clinical successes were achieved in 100% and 87.3% of patients, respectively. The gastric outlet obstruction scoring system score significantly improved after stent placement (from median 1 to 2, P < 0.001). The median duration of stent patency was 147 days (interquartile range 76-201), and median duration of overall survival was 176 days (interquartile range 79-325). Stent migration was observed in seven patients (11.1%), and restenosis was developed in 12 patients (19.0%). All cases of migration were proximal, and no distal migration was observed. Endoscopic removal of migrated stents was performed successfully in all cases.

conclusionsThe newly designed winged stent showed feasible efficacy and safety for malignant gastric outlet obstruction. Furthermore, it effectively prevented distal stent migration.
