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 impact of the number of negative lymph nodes (LNs) on survival in patients with esophageal cancer remains a controversial issue. This study investigated the association between the number of resected LNs and the prognosis of patients with node-negative esophageal carcinoma.

methodsA retrospective review was performed of the data of 429 patients who underwent esophagectomy with modern two-field lymphadenectomy for the treatment of esophageal cancer between January 1998 and December 2008. Histopathology showed no LN involvement in the patient sample. The prognostic impact of the number of negative LNs and the clinicopathological factors were analyzed.

resultsThe overall median survival time and the one, three, and five-year overall survival rates were 63.0 months and 78.5%, 64.0%, and 51.2%, respectively. Survival analysis confirmed that the number of negative LNs and the depth of tumor invasion were independent prognostic factors. Patients with a high number of negative LNs had a better overall survival rate than patients with a low number of negative LNs (P < 0.001). Patients with dissected LNs > 14 for pT1 tumors (P < 0.001) and > 19 for pT2-3 tumors (P < 0.001 and P = 0.001, respectively) had better long-term survival outcomes.

conclusionsThe number of negative LNs is an independent prognostic factor for node-negative esophageal carcinoma. Extended LN dissection is recommended to improve the survival of patients with node-negative esophageal carcinoma.
