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

backgroundEsophageal squamous cell carcinoma (ESCC) is prevalent in East Asia, with elderly patients facing unique postoperative challenges. This study examines the impact of seasonal variations on postoperative complications and survival in elderly patients undergoing esophagectomy for ESCC.

methodsThis retrospective cohort study was conducted using data from the Sichuan Cancer Hospital & Institute Esophageal Cancer Case Management Database. Elderly patients (≥ 70 years) with thoracic ESCC who underwent esophagectomy between May 2016 and August 2021 were included. Patients were stratified into four seasonal groups: Winter (December-February), Spring (March-May), Summer (June-August), and Autumn (September-November). Primary outcomes included overall survival (OS), disease-free survival (DFS). Secondary outcomes assessed postoperative complications using the Clavien-Dindo classification.

resultsA total of 469 elderly ESCC patients were included. The median overall survival was 51.6 months, with no significant differences in OS or DFS across the four seasonal groups. Restricted Mean Survival Time (RMST) and Restricted Mean Disease-Free Survival Time (RMDFST) analyses also showed no significant seasonal variations. The Summer group had a significantly higher incidence of hydrothorax compared to other groups (p < 0.05).

conclusionsSeasonal variations influence specific short-term postoperative complications but do not significantly impact long-term survival in elderly ESCC patients undergoing esophagectomy.
