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

backgroundThoracoscopic esophagectomy (TE) is considered the standard surgery for esophageal cancer because of its superiority over open esophagectomy (OE) in terms of short-term outcomes. However, few prospective multicenter studies have evaluated its long-term survival after TE. This study aimed to investigate whether the prognosis for patients with T1bN0M0 esophageal cancer after TE is not inferior to OE using data from the Japan Clinical Oncology Group Study (JCOG0502), a prospective multicenter trial comparing esophagectomy with chemoradiotherapy.

methodsData of patients in JCOG0502 after esophagectomy were used to compare the overall survival (OS) and relapse-free survival (RFS) after OE versus TE. OE or TE was selected at the surgeon's discretion. A hazard ratio and 95% confidence interval (CI) were calculated via Cox proportional-hazards model.

resultsOf the 210 patients who underwent esophagectomy, 109 underwent OE, whereas 101 underwent TE. The 5-year OS was 88.9% after OE and 85.0% after TE. The hazard ratio of TE for OS was 1.53 (95% CI, 0.84-2.78; p = 0.16) and 1.10 (95% CI, 0.52-2.35; p = 0.80) in the univariable and multivariable analyses, respectively. The 5-year RFS was 85.3% after OE and 79.1% after TE. The hazard ratio of TE for RFS was 1.39 (95% CI, 0.81-2.38; p = 0.23) and 0.88 (95% CI, 0.44-1.74; p = 0.70) in the univariable and multivariable analyses, respectively.

conclusionThe prognosis for patients with T1bN0M0 esophageal cancer after TE was not inferior to OE.
