Adequate lymphadenectomy for colorectal cancer: a comparative analysis between open and laparoscopic surgery.
Observational study in Arquivos brasileiros de cirurgia digestiva : ABCD = Brazilian archives of digestive surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundIn the surgical treatment of colorectal cancer, a lymphadenectomy is considered adequate when at least 12 lymph nodes are removed.
aimTo evaluate whether videolaparoscopic surgery positively affects the rates of adequate lymphadenectomy.
methodsAn observational study was conducted with patients undergoing either open or videolaparoscopic surgery for colorectal cancer between 2008 and 2013. The following variables were collected: gender, age, tumor site, histology, degree of differentiation, tumor stage, number of lymph nodes removed, and number of lymph nodes affected by the disease.
resultsA total of 62 patients with colorectal cancer were included; 42 (67.7%) received open surgery, and 20 (32.3%) laparoscopic surgery. Regarding lymphadenectomy, a mean of 13 lymph nodes (95% CI: 10-16) were removed in the group that received open surgery, while 19 lymph nodes were removed (95% CI: 14-24) in the laparoscopic surgery group (p=0.021). Adequate lymphadenectomy (removal of at least 12 lymph nodes) was achieved in 58.1% of the total cases, in 50.0% of the patients who received open surgery, and in 75% of those who received laparoscopic surgery. Non-elderly patients and those with an advanced disease stage were more likely to receive an adequate lymphadenectomy (p=0.004 and p=0.035, respectively).
conclusionDisease stage and patient age were the factors that had the greatest influence on achieving an adequate lymphadenectomy. The type of surgery did not affect the number of lymph nodes removed.
