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

backgroundApproximately, 22.6% of colorectal cancer surgeries were performed on patients aged 80 or over. The present study aimed to evaluate the use of laparoscopic resection and its short-term surgical outcomes in patients who were aged 80 and older and diagnosed with colon cancer or rectal cancer in parallel.

methodsIn this retrospective population-based study, colon and rectal cancer patients ≥ 80 years undergoing laparoscopic resection or open resection were identified from the United States National Inpatient Sample (2005-2014). Primary outcomes were postoperative complication and in-hospital mortality. Logistic regression analyses were performed to assess the short-term effectiveness of laparoscopic and open resection.

resultsIn this study, 40,451 colon cancer patients and 1117 rectal cancer patients were included. Multivariate analysis revealed that laparoscopic resection was significantly associated with lower risks for developing postoperative complications (aOR = 0.67; 95%, CI 0.64-0.71) and in-hospital mortality (aOR = 0.37; 95% CI 0.32-0.43) compared to open resection in colon cancer patients. For rectal cancer patients, multivariate analysis indicated that laparoscopic resection was significantly associated with a lower risk of developing postoperative complications (aOR = 0.41; 95% CI 0.32-0.52) but was not associated with in-hospital mortality.

conclusionCompared to open resection, laparoscopic resection has better or similar short-term surgical outcomes in colon and rectal cancer patients ≥ 80 years.
