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

backgroundConflicting data have been reported on the prognostic impact of the extent of lymphadenectomy during esophagectomy for esophageal cancer (EC) after neoadjuvant therapy, especially after neoadjuvant chemoradiotherapy (nCRT).

methodsA comprehensive online search was performed to explore the association between increased lymph node yield (LNY) and survival of patients with EC, in which the overall survival (OS) was set as the primary outcome. In addition to analysis of the entire cohort, subgroup analyses of different induction therapy and different populations were also performed.

findingsA total of 19528 patients from twelve studies were included in our study. The pooled data revealed that more lymph node harvested was associated with better OS (HR = 0·87; 95% CI: 0·79-0·95,

interpretationIncreased LNY during esophagectomy after neoadjuvant therapy, especially after nCRT, might be associated with improved OS. More studies are warranted to assess the survival benefits of a higher LNY receiving neoadjuvant therapy plus esophagectomy, especially in Eastern populations.
