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

backgroundAccumulating evidence suggests a survival benefit after curative oesophageal cancer surgery in women compared with men. The aim of this study was to explore sex disparities in survival after surgery with curative intent in patients with oesophageal cancer.

methodsThis was a population-based cohort study, including all patients with oesophageal or gastric cancer who underwent surgery with a curative intent between 2006 and 2017 in Sweden. Female versus male mortality rate ratio (MRR) and excess mortality rate ratio (EMRR) were used as measures of survival. Two different parametric models were designed to account for potential confounders. Patients with gastric cancer were used as a comparison group as no differences in survival between sexes were expected among these patients.

resultsA total of 1301 patients underwent resection for oesophageal adenocarcinoma and 305 patients for oesophageal squamous cell carcinoma. Women had a lower EMRR (0.76, 95 per cent c.i. 0.58 to 1.01, P = 0.056; 0.52, 95 per cent c.i. 0.32 to 0.84, P = 0.007 respectively) in both histological subtypes. The effect was more profound in early clinical stages, in patients receiving neoadjuvant treatment, and without postoperative complications. No sex-related difference was observed in survival of patients with gastric cancer.

conclusionsWomen undergoing resection for oesophageal carcinoma have better survival compared with men.
