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
backgroundRadiotherapy (RT) is preferred over stent placement for dysphagia in unresectable esophageal squamous cell carcinoma (ESCC); however, low-radial-force self-expandable metallic stents (SEMS) may offer safer and more effective palliation. We aimed to compare the outcomes of RT and low-radial-force SEMS in ESCC patients.
methodsThis retrospective study included patients with unresectable ESCC and dysphagia who underwent palliative RT or low-radial-force SEMS placement between 2013 and 2023. Adverse events were compared, and treatment efficacy was assessed based on changes in Dysphagia Score (DS) and the duration of maintaining DS ≤ 1 among those who achieved it.
resultsThe stent and RT groups comprised 34 and 45 patients, respectively. Treatment-related adverse events of Grade ≥ 2 and ≥ 3 occurred in 29.4% and 5.8% in the stent group and 34.9% and 6.7% in the RT group, respectively, with no significant differences. After adjustment for baseline DS, the stent group showed significantly greater improvement at 1 month (p < 0.001), whereas no differences were observed at 2 or 3 months. DS ≤ 1 was achieved in 76.5% with stent and 44.4% with RT (p = 0.006). Maintenance of DS ≤ 1 was shorter with stent group when additional SEMS placement was considered an event (p = 0.006), whereas no difference was observed when additional SEMS was allowed (p = 0.898).
conclusionLow-radial-force SEMS is safe and effective for dysphagia in unresectable advanced ESCC, especially when early oral intake is needed, and can help prolong oral intake if additional SEMS is allowed.
