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

backgroundLigation of the thoracic duct (LTD) is known to be a useful way to prevent postoperative chylothorax, but its impact on long-term survival is rare to be assessed.

methodsData from 609 patients with esophageal cancer who underwent esophagectomy from September, 2012, to January, 2014, were retrospectively collected. The study cohort was classified into two groups: the thoracic duct ligation group (LG) and the non-ligation group (NLG). Propensity score matching (PSM) was performed to control confounding factors between the two groups. Postoperative complications and length of stay were compared between the two groups. Overall survival was estimated using the Kaplan-Meier method, and compared using the log-rank test. Independent prognostic factors were determined using Cox regression analysis.

resultsAfter PSM, there were 185 patients in each of the two groups. LTD had no significant impact on chylothorax, anastomotic leak, recurrent nerve palsy, pneumonia and length of stay (P>0.05). The 1-, 3- and 5-year survival rates were 87.0%, 64.1%, and 50.9% in the LG, respectively, compared to 85.4%, 59.9%, and 42.3%, respectively, in the NLG. The differences between the 2 groups were not statistically significant (P=0.156). In the multivariable analysis, LTD was not an independent prognostic factor, neither before nor after PSM.

conclusionsOur study demonstrated that LTD had no significant impact on postoperative complications or long-term survival in patients with esophageal cancer.
