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

backgroundLittle is known about the prognostic significance of residual nodal disease in otherwise complete pathologic responders (ypT0N+) after neoadjuvant chemoradiation (nCRT) for esophageal cancer (EC). The purpose is to analyze the long-term outcomes of EC patients with ypT0N+ following nCRT and esophagectomy.

methodsFrom a single institution database, 466 consecutive EC patients undergoing esophagectomy after nCRT were collected (1996-2016). ypT0N+ responders were compared to pathological complete responders (ypT0N0) and to pathological non-complete responders (ypT+N0 and ypT+N+).

resultsThere were 149 ypT0N0, 31 ypT0N+, 141 ypT+N0 and 145 ypT+N+. Median overall survival (OS) was worse in ypT0N+ (21.7 months) and ypT+N+ (16.8 months) compared to ypT0N0 (55.2 months) and ypT+N0 (42.0 months). Stratification by histology revealed a significant difference in prevalence of ypT0: 62.5% in 184 squamous cell carcinomas (SCC) compared to 23.0% in 282 adenocarcinomas (ADC) (P<0.0001) but not in ypT0N+ (15%

conclusionsypT0N+ in EC patients following nCRT has a poor prognosis and behaves similar to ypT+N+. However, stratification by histology shows that this is especially true in ADC but seems determined by the number of involved lymph nodes.
