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.
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
backgroundUncertainties persist regarding the allocation of apical lymph nodes in colorectal cancer, the approaches to lymph node dissection and mesocolic excision, which may contribute to inconsistent surgical practices. The aim of this study is to assess surgeons' practices in lymph node dissection and mesocolic excision approaches and to identify areas lacking standardization.
methodsA multinational pilot survey of 22 colorectal surgeons from 6 countries was conducted during the FICARE colorectal meeting. The survey consisted of 21 Likert-scale questions on surgical practices and lymph node allocation in colorectal cancer surgery.
resultsMajority of the respondents (90.9%) recognized conceptual differences in apical lymph node stratification between right- and left-sided colon cancers, whereas D3 LND for left-sided cancer should include mesocolic tissue along the inferior mesenteric artery from its origin to the last sigmoid artery. Complete lymph node dissection requires excision of mesocolic tissue along inferior mesenteric artery for left colon cancer and superior mesenteric artery for right colon cancer according to 81.8% of respondents. At the same time, 95.5% agreed that intermediate and paracolic lymph nodes are located within a 10-cm resection margin proximally and distally from tumor, while 81.9% of respondents supported the concept of tumor-specific mesocolic excision to be sufficient enough for adequate paracolic and intermediate lymph node dissection.
conclusionsA multinational snapshot showed an existing contraindication in surgeons' perception of lymph node stratification and the variability in mesocolic excision and LND. Further Delphi consensus is needed to prove the suggested concepts.
