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

objectivesthe surgical approach persists as the main treatment for esophageal cancer. This study compares the patients of the same institution over time at three different times.

methodsthis is a retrospective, observational, descriptive study comparing the surgical outcomes obtained by the Division of Surgical Oncology of Erasto Gaertner Hospital. The sample was divided into Period 1 (1987-1997), Period 2 (1998-2003) and Period 3 (2007-2015). Survival rates and disease-free survival were estimated by the Kaplan-Maier method. Survival predictors were identified with Cox regression. ANOVA test was used for comparison between groups. Data were analyzed with SPSS 25.0 and STATA 16, and p<0.05 was considered statistically significant.

resultsa total of 335 patients underwent esophagectomy or esophagogastrectomy. When the clinical characteristics of the 3 groups were compared, there was no statistically significant difference. Neoadjuvance was significantly higher in Period 3 (55.4% of patients). We found a histological change in the diagnosis over time, with a significant increase in adenocarcinoma. Morbidity and mortality rates were higher in Period 3. The main complications were pulmonary and anastomotic fistulas. Overall survival in 5 years increased over time, reaching 59.7% in Period 3.

conclusionsbetter neoadjuvant treatment contributed to increase the global survival of patients, despite greater rate of immediate complications to surgery.
