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

backgroundThe most frequent site for the extranodal appearance of primary non-Hodgkin's lymphomas (NHL) is the gastrointestinal (G.I.) tract. However, primary esophageal lymphoma is extremely rare. The purpose of the present study was to describe and analyze the demographics, clinical characteristics, histopathologic types, and long-term survival of patients with primary esophageal NHL registered in the surveillance, epidemiology, and end results (SEER) database.

methodsRetrospective cohort study. Individuals with primary esophageal lymphoma (PEL) were identified using the international classification of disease for oncology, third edition histology codes. Patients were excluded if there was no microscopic confirmation of the neoplasm or if the diagnosis was made by autopsy or death certificate. Data on demographics, clinical characteristics, histopathology and survival were analyzed using the Kaplan-Meier method, life table, and cox proportional hazard models.

results179 patients were included (68% males, median age 66 years [IQR 46-79]). The overall survival at 1, 5 and 10 years was 65% (95% CI 57.9-72.3%), 49% (95% CI 42.1-57.3%), and 31% (95% CI 24.5-38.6%), respectively. On univariate analyses, individuals with extranodal marginal zone lymphoma (MZL) had a significantly higher overall survival when compared to patients with diffuse large B cell lymphoma (HR 0.29; 95% CI 0.11-0.73. p = 0.008). Furthermore, patients whose cancer was diagnosed after 1997 showed an improved overall survival (HR 0.40; 95% CI 0.26-0.61. p < 0.001) when compared to those diagnosed before 1997.

conclusionsIn this large population-based series, diagnosis after 1997 (year of rituximab approval by the FDA) and MZL subtype were associated with improved survival outcomes in patients with PEL.
