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 role of adjuvant chemotherapy in esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to evaluate the impact of adjuvant chemotherapy on survival in patients with positive nodes after surgery for ESCC.

methodsWe retrospectively reviewed the survival outcomes of node-positive patients with ESCC who underwent curative resection with or without adjuvant chemotherapy between January 1994 and December 2015.

resultsWe analyzed 460 patients (333 adjuvant chemotherapy, 127 surgery alone). The surgery-alone group was older (64 vs. 60 years, p < 0.001) and had more comorbidities (p = 0.004) than the adjuvant chemotherapy group. After propensity score matching, overall survival (OS) and recurrence-free survival (RFS) of the adjuvant chemotherapy group were better than those of the surgery-alone group: 5-year OS rate 62.7% (95% confidence interval [CI] 54.4-72.3%) vs. 46.8% (95% CI 38.5-57%, p = 0.001) and 5-year RFS rate 53.9% (95% CI 45.4-63.9%) vs. 36.2% (95% CI 28.3-46.3%, p < 0.001). Notably, in patients with pT3-4 stage, the adjuvant chemotherapy group had significantly better 5-year OS rate (41.3% [95% CI 29.3-58.3%] vs. 18% [95% CI 10-32.5%], p = 0.01) and 5-year RFS rate (37% [95% CI 25.3-53.9%] vs. 12% [95% CI 5.7-25.4%], p < 0.001) than in the surgery-alone group. In multivariable analysis, adjuvant chemotherapy had a favorable effect on both OS (hazard ratio [HR] 0.562, 95% CI 0.426-0.741, p < 0.001) and RFS (HR 0.702, 95% CI 0.514-0.959; p = 0.026).

conclusionAdjuvant chemotherapy may improve survival in node-positive patients with ESCC, especially in those with pT3-4 stage.
