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

backgroundThoracoscopic esophagectomy is rapidly and increasingly being used worldwide because it is a less invasive alternative to open esophagectomy. However, few prospective multicenter studies have evaluated its safety profile. This study aimed to evaluate the safety profile of thoracoscopic esophagectomy using perioperative data from the Japan Clinical Oncology Group Study (JCOG0502).

methodsJCOG0502 is a four-arm prospective study comparing esophagectomy with chemoradiotherapy for esophageal cancer, with randomized and patient preference arms. Patients with clinical stage T1bN0M0 esophageal cancer were enrolled until patient accrual was completed. Open or thoracoscopic esophagectomy was selected at the surgeon's discretion. Perioperative complications were defined as adverse events of ≥grade 2 as per Common Terminology Criteria for Adverse Events ver. 3.0.

resultsA total of 379 patients were enrolled between December 2006 and February 2013. Of the 210 patients who underwent surgery, 109 patients underwent open esophagectomy, and 101 patients underwent thoracoscopic esophagectomy. Although thoracoscopic esophagectomy decreased the incidence of postoperative atelectasis (open: 22.0%, thoracoscopy: 10.9%; P = 0.041), reoperation was more frequent in the thoracoscopy group (open: 1.8%, thoracoscopy: 9.9%; P = 0.016). The incidence of overall complications did not differ between the two groups (open: 44.0%, thoracoscopy: 44.6%; P = 1.00). There was one in-hospital death in each group (open: 0.9%, thoracoscopy: 1.0 %; P = 1.00).

conclusionsThoracoscopic esophagectomy is a safe procedure with morbidity and mortality comparable with those of open esophagectomy. However, it is associated with a higher frequency of reoperation.
