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

backgroundAn increasing number of older patients is undergoing curative, surgical treatment of esophageal cancer. Previous meta-analyses have shown that older patients suffered from more postoperative morbidity and mortality compared to younger patients, which may lead to patient selection based on age. However, only studies including patients that underwent open esophagectomy were included. Therefore, it remains unknown whether there is an association between age and outcome in patients undergoing minimally invasive esophagectomy.

aimTo perform a systematic review on age and postoperative outcome in esophageal cancer patients undergoing esophagectomy.

methodsStudies comparing older with younger patients with primary esophageal cancer undergoing curative esophagectomy were included. Meta-analysis of studies using a 75-year age threshold are presented in the manuscript, studies using other age thresholds in the Supplementary material. MEDLINE, Embase and the Cochrane Library were searched for articles published between 1995 and 2020. Risk of bias was assessed with the Newcastle-Ottawa Scale. Primary outcomes were anastomotic leak, pulmonary and cardiac complications, delirium, 30- and 90-d, and in-hospital mortality. Secondary outcomes included pneumonia and 5-year overall survival.

resultsSeven studies (4847 patients) using an age threshold of 75 years were included for meta-analysis with 755 older and 4092 younger patients. Older patients (9.05%) had higher rates of 90-d mortality compared with younger patients (3.92%), (confidence interval = 1.10-5.56). In addition, older patients (9.45%) had higher rates of in-hospital mortality compared with younger patients (3.68%), (confidence interval = 1.01-5.91). In the subgroup of 2 studies with minimally invasive esophagectomy, older and younger patients had comparable 30-d, 90-d and in-hospital mortality rates.

conclusionOlder patients undergoing curative esophagectomy for esophageal cancer have a higher postoperative mortality risk. Minimally invasive esophagectomy may be important for minimizing mortality in older patients.
