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

backgroundHead and neck squamous cell carcinoma (HNSCC) have poor outcomes in advanced stages. Early detection and minimally invasive treatment are essential. Endoscopic laryngo-pharyngeal surgery (ELPS), guided by narrowband imaging, is widely used in Asia, but its prognostic value remains unclear.

methodsWe retrospectively analyzed 111 patients with superficial HNSCC who were treated with ELPS between 2014 and 2023. Patient background, treatment results, complications, and prognostic factors were assessed.

resultsThe median observation period was 56 months. En bloc resection was achieved in 96.4% of cases, and the 5-year overall survival (OS) was 91.6%. Tumor thickness > 1000 μm was associated with metastasis in univariate analysis, whereas multivariate analysis identified tumor size > 20 mm and lymphatic invasion as independent predictors. Patients with a body mass index < 18.5 had poorer OS, primarily owing to comorbidities rather than HNSCC. Adverse events occurred in 26.1% of patients, most of which were transient laryngeal edema. One patient required a temporary tracheotomy, but no permanent tracheostomy was needed. ELPS was feasible and safe, even in patients with prior chemoradiotherapy (CRT), as no fatal complications were observed.

conclusionsELPS provides favorable mid- to long-term outcomes and can be safely applied to selected patients, including those with prior CRT. Tumor size and lymphatic invasion are key prognostic factors. These findings support ELPS as a minimally invasive, function-preserving treatment option for superficial HNSCC with careful patient selection.
