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

purposeIt is well known that an increased body mass index (BMI) is associated with cancer development. Results from studies on colorectal cancer (CRC) treatment outcome and BMI are however conflicting. Our hypothesis was that a high as well as a low BMI will have negative effects on short-term outcome after CRC surgery.

methodsData from the Swedish Colorectal Cancer Registry from 2007 to 2012 was analyzed. A total of 24,587 patients operated on for CRC were included in the study and divided into one of five categories for BMI. Operative bleeding, operating time, surgical complications, and 30-day mortality were compared between groups.

resultsOperative bleeding as well as operating time was significantly increased when comparing normal-weight patients to overweight (p < 0.001). 15.1% of normal-weight patients suffered from postoperative surgical complications. This was significantly increased with each BMI step but did not affect the 30-day mortality. However, underweight patients, on the other hand, had fewer complications (13.3%) but an increased 30-day mortality.

conclusionLonger operating times and increased perioperative bleeding may be explanatory factors behind increased postoperative complication rates for CRC patients with higher BMI. In underweight patients, advanced disease may be a reason for a higher 30-day mortality. To improve outcome, specific precautions are suggested when operating on under- as well as overweight CRC patients. We also suggest that the registry introduces a better marker than BMI for central visceral fat-the link between obesity and cancer development. Further studies are needed to analyze the findings in detail and to study long-term effects.
