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

backgroundRandomized trials show similar outcomes after open surgery and laparoscopy for colon cancer, and confirmation of outcomes after implementation in routine practice is important. While some studies have reported long-term outcomes after laparoscopic surgery from single institutions, data from large patient cohorts are sparse. We investigated short- and long-term outcomes of laparoscopic and open surgery for treating colon cancer in a large national cohort.

methodsWe retrieved data from the Norwegian Colorectal Cancer Registry for all colon cancer resections performed in 2007-2010. Five-year relative survival rates following laparoscopic and open surgeries were calculated, including excess mortality rates associated with potential predictors of death.

resultsAmong 8707 patients with colon cancer that underwent major resections, 16 % and 36 % received laparoscopic procedures in 2007 and 2010, respectively. Laparoscopic procedures were most common in elective surgeries for treating stages I-III, right colon, or sigmoid tumours. The conversion rate of laparoscopic procedures was 14.5 %. Among all patients, laparoscopy provided higher 5-year relative survival rates (70 %) than open surgery (62 %) (P = 0.040), but among the largest group of patients electively treated for stages I-III disease, the approaches provided similar relative survival rates (78 vs. 81 %; P = 0.535). Excess mortality at 2 years post-surgery was lower after laparoscopy than after open surgery (excess hazard ratio, 0.7; P = 0.013), but similar between groups during the last 3 years of follow-up. Major predictors of death were stage IV disease, tumour class pN+, age > 80 years, and emergency procedures (excess hazard ratios were 5.3, 2.4, 2.1, and 2.0, respectively; P < 0.001).

conclusionNationwide implementation of laparoscopic colectomy for colon cancer was safe and achieved results comparable to those from previous randomized trials.
