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 study was done to determine long-term outcomes of surgically treated esophageal cancer and to identify trends in epidemiology, oncological therapy, and oncological prognosis over the last two decades.

methodsOverall survival in 304 patients undergoing esophagectomy was analyzed. Fifty-three percent had squamous cell carcinoma and 46 % had adenocarcinoma (AC). A total of 161 patients received neoadjuvant chemoradiation, 38 received neoadjuvant chemotherapy, and 105 were treated with surgery alone.

resultsMedian survival (MS) increased significantly from 18.0 months (1988-1994) to 26.6 months (1995-2001) and to 59.3 months (2002-2011; p < 0.001). The proportion of AC (22 vs 35 vs 65 %; p < 0.001) and the proportion of patients treated with neoadjuvant therapy (neoT; 15.9 vs 85.3 vs 77.8 %; p < 0.001) increased during the treatment period. After neoT, a beneficial outcome with a MS of 45.6 vs. 20.4 months (p = 0.003) was found. Lymph node ratio [LNR; relative risk (RR), 5.4; p < 0.001], response to neoT (RR, 1.6; p < 0.004), and histological subtype (RR, 1.7; p < 0.003) were identified as independent parameters of survival.

conclusionSince 1988, the outcome of surgically resected esophageal cancer strongly improved. Besides tumorbiological factors like histological type and LNR, the outcome is also affected by the increasing use of neoT towards favorable survival rates.
