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 optimal time interval between neoadjuvant chemoradiotherapy (nCRT) and esophagectomy in esophageal cancer has not been defined.

aimTo evaluate whether a prolonged time interval between the end of nCRT and surgery has an effect on survival outcome in esophageal cancer patients.

methodsWe searched PubMed, Embase, Web of Science, the Cochrane Library, Wanfang and China National Knowledge Infrastructure databases for relevant articles published before November 16, 2019, to identify potential studies that evaluated the prognostic role of different time intervals between nCRT and surgery in esophageal cancer. The hazard ratios and 95% confidence intervals (95%CI) were merged to estimate the correlation between the time intervals and survival outcomes in esophageal cancer, esophageal squamous cell carcinoma and adenocarcinoma using fixed- and random-effect models.

resultsThis meta-analysis included 12621 patients from 16 studies. The results demonstrated that esophageal cancer patients with a prolonged time interval between the end of nCRT and surgery had significantly worse overall survival (OS) [hazard ratio (HR): 1.107, 95%CI: 1.014-1.208,

conclusionA prolonged time interval from the completion of nCRT to surgery is associated with a significant decrease in OS. Thus, esophagectomy should be performed within 7-8 wk after nCRT.
