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.

Abstract

backgroundLaparoscopic surgery has been widely accepted for the treatment of colorectal cancer; however, long-term outcomes in elderly patients remain controversial. The midterm results of a randomized trial comparing open surgery with laparoscopic surgery in elderly patients with colorectal cancer are presented.

methodsThis was a randomized trial comparing open surgery with laparoscopic surgery in elderly patients with colorectal cancer. The primary outcome was complication rate, and secondary outcomes included 3-year recurrence-free survival and overall survival. A total of 200 patients were randomly assigned to open surgery or laparoscopic surgery between 2008 and 2012. The main study objective was to compare the midterm outcomes of open surgery with those of laparoscopic surgery in elderly patients with colorectal cancer. This trial is registered with Clinical Trials.gov (NCT01862562).

resultsThere were no differences between the laparoscopic surgery group and open surgery group in the 3-year overall survival rate (91.5% for laparoscopic surgery vs. 90.6% for open surgery, p = 0.638) or the 3-year recurrence-free survival rate (84.8% for laparoscopic surgery vs. 88.2% for open surgery, p = 0.324). The local recurrence rate was significantly higher in the laparoscopic surgery group than in the open surgery group in rectal cancer (13.8% for laparoscopic surgery vs. 0% for open surgery, p = 0.038). In subgroup analysis according to tumor location, there were no significant differences in the 3-year overall survival rate or 3-year recurrence-free survival rate between the two treatment groups.

conclusionThe midterm outcomes of laparoscopic surgery are similar to those of open surgery in elderly patients with colorectal cancer.
