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

backgroundStudies have shown that epidural analgesia (EDA) is associated with a decreased risk of pneumonia and anastomotic leakage after esophagectomy, and several guidelines strongly recommend EDA use after esophagectomy. However, the benefit of EDA use in minimally invasive esophagectomy (MIE) remains unclear.

objectiveThe aim of this retrospective study was to compare the short-term outcomes between patients with and without EDA undergoing MIE for esophageal cancer.

methodsData of patients who underwent oncologic MIE (April 2014-March 2019) were extracted from a Japanese nationwide inpatient database. Stabilized inverse probability of treatment weighting (IPTW), propensity score matching, and instrumental variable analyses were performed to investigate the associations between EDA use and short-term outcomes, adjusting for potential confounders.

resultsAmong 12,688 eligible patients, EDA was used in 9954 (78.5%) patients. In-hospital mortality, respiratory complications, and anastomotic leakage occurred in 230 (1.8%), 2139 (16.9%), and 1557 (12.3%) patients, respectively. In stabilized IPTW, EDA use was significantly associated with decreased in-hospital mortality (odds ratio [OR] 0.46 [95% confidence interval 0.34-0.61]), respiratory complications (OR 0.74 [0.66-0.84]), and anastomotic leakage (OR 0.77 [0.67-0.88]). EDA use was also associated with decreased prolonged mechanical ventilation, unplanned intubation, nonsteroidal anti-inflammatory drug use, acetaminophen use, postoperative length of stay, and total hospitalization costs and increased vasopressor use. One-to-three propensity score matching and instrumental variable analyses demonstrated equivalent results.

conclusionsEDA use in oncologic MIE was associated with low in-hospital mortality as well as decreased respiratory complications, and anastomotic leakage, suggesting the potential advantage of EDA use in MIE.
