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 cancer (SmCC) of the esophagus is a rare malignancy with an aggressive behavior associated with poor survival. The present study aims to determine the clinicopathological characteristics, therapeutic and prognosis.

methodsPatients with SmCC of the esophagus, diagnosed from 1975 to 2016, were identified from the Surveillance, Epidemiology, and End Results (SEER) database. The clinicopathological characteristics were described and the prognostic factors were further determined using Cox regression analysis.

resultsThe median overall survival (mOS) of all 515 patients with SmCC of the esophagus was 7.0 months, and the 1-, 2-, and 5-year survival rates were 31.5%, 14.7%, 6.00%, respectively. Patients with chemoradiotherapy (mOS: 12.0 months) had better prognosis than those receiving surgery alone (mOS: 12.0

conclusionsSmCC of the esophagus is uncommon, older age and distant metastases were independently associated with poor survival. Chemotherapy could provide significant clinical benefit for those patients, especially chemoradiotherapy and surgery combined with chemotherapy.
