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

backgroundAlong with an aging society, the number of elderly patients with colorectal cancer treated with a surgical modality has gradually increased. Our purpose is to verify the safety and effectiveness of laparoscopic surgery for the treatment of colorectal cancer in elderly patients.

methodsWe compared the short-term outcomes of open versus laparoscopic surgery in patients aged 80 years or older with colorectal cancer between 2007 and 2014.

resultsOf 150 elderly colorectal patients, 62 patients received laparoscopic surgery, and 88 patients, open surgery. In the laparoscopic surgery group, two patients were converted to open surgery due to extensive adhesion. The amount of blood loss was smaller in patients treated with laparoscopic surgery than those with open surgery (44.0 ± 86.5 vs. 329.9 ± 482.1 ml, P < 0.01). In the laparoscopic surgery group, days until oral intake (5.3 ± 1.9 vs. 7.0 ± 3.0 days, P < 0.01) and hospital stay (17.2 ± 6.8 vs. 22.0 ± 14.0 days, P < 0.01) were shorter. Morbidity (30.6 vs. 42.0 %) and mortality (1.6 vs. 1.1 %) in laparoscopic and open surgery groups were similar.

conclusionLaparoscopic surgery in elderly patients with colorectal cancer was a safe and less invasive alternative to open surgery, with less blood loss and shorter hospital stay.
