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

BACKGROUND AND

aimsSelf-expanding metal stents (SEMSs) are effective for symptom palliation in patients with esophageal obstruction. However, their placement can lead to adverse events such as stent migration and restenosis. A novel fully covered SEMS (FCSEMS) with antimigration properties has been developed to address these issues. This study aimed to evaluate the feasibility and safety of this novel stent in treating malignant esophageal obstruction.

methodsThis prospective pilot study enrolled patients with malignant esophageal obstruction treated with the novel stent at a tertiary referral center. Primary outcomes included technical and clinical efficacy, whereas secondary outcomes were adverse events. Treatment outcomes were compared between the novel stent and historical control groups.

results137 patients were analyzed, comprising 32 in the novel stent group and 105 in the historical control group. In the novel stent group, technical success was achieved in 100% of patients and clinical success in 96.9%. No stent placement-related events, including bleeding or perforation, were observed. Though no significant differences in adverse events were found, the novel stent group had a lower migration rate than the historical control group (9.4% vs. 14.3%, p = 0.565). Median stent patency was similar between the groups (70.5 vs. 43.0 days, p = 0.185).

conclusionsThe novel multisegmented FCSEMS demonstrated high technical and clinical efficacy with a low migration rate, presenting a promising treatment option for malignant esophageal obstruction. Further studies with larger samples are needed to confirm these findings.
