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

purposeEsophagectomy for esophageal cancer is a very invasive surgery that induces an intense systemic inflammatory response. Postoperative infectious complications worsen survival after esophagectomy through inflammatory responses, and this study aimed to investigate the impact of the response on disease recurrence.

methodsWe assessed 230 patients who underwent curative minimally invasive esophagectomy for esophageal squamous cell carcinoma. The area under the curve of serum C-reactive protein levels from preoperative day through postoperative day 7 was defined as the cumulative magnitude of postoperative inflammatory response.

resultsRelapse-free survival was compared among quartiles of the area, and fourth quartile showed the worst relapse-free survival. Patients in the fourth quartile were the high group, and others were low group. Compared with low group (n = 173), high group (n = 57) showed significantly worse relapse-free survival and overall survival (P = 0.014 and 0.028, respectively). Multivariate analyses found that high group (P = 0.048) was an independent risk factor for recurrence but not overall survival. Higher body mass index (P < 0.001) and postoperative infections (P < 0.001) were independent risk factors to become high group. However, the influence of high group on recurrence was not affected by postoperative infections in interaction analysis (P = 0.889).

conclusionsPostoperative intense systemic inflammatory response independently increased the risk of recurrence after curative minimally invasive esophagectomy for esophageal squamous cell carcinoma. Factors associating with intensified inflammatory response are higher body mass index and postoperative infections. Therefore, surgeons should make every effort to prevent postoperative infections to improve the long-term outcomes of patients.
