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

backgroundSmall cell carcinoma of the esophagus is a rare malignant tumor. We aimed to explore the chemotherapeutic efficacy on the prognosis of patients with small cell carcinoma of the esophagus who received radiotherapy.

methodsTo identify the population of interest, Surveillance, Epidemiology, and End Results data from 1996 to 2016 were chosen. Univariate and multivariate analyses were used to probe into prognosis factors. Multivariate Cox regression analysis was conducted to identify factors related to overall survival and cancer-specific survival.

resultsOverall, data from 162 patients were analyzed in this study. Tumor size (P = 0.014), T staging (P = 0.028), and chemotherapy (P < 0.001) were independent prognostic factors affecting overall survival. Patients with regional disease (hazard ratio = 5.435, P < 0.001) and distant metastasis (hazard ratio = 2.183, P < 0.001) who received radiotherapy alone had worse survival than those receiving chemoradiotherapy. Tumor size (P = 0.004) and chemotherapy (P < 0.001) were independent prognostic factors affecting cancer-specific survival. Tumor size was an independent factor affecting cancer-specific survival for patients receiving chemoradiation.

conclusionsAge, T staging, tumor size, primary site, and chemotherapy are independent prognosis factors affecting overall survival and cancer-specific survival in patients with small cell carcinoma of the esophagus who receive radiotherapy. Chemotherapy might further improve cancer-specific survival in patients with small cell carcinoma of the esophagus receiving radiotherapy at all stages.
