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

purposeThe benefits of laparoscopic surgery for colorectal cancer have been well established. Several randomized controlled trials have demonstrated similar oncological outcomes between laparoscopic and open surgery for colon cancer. However, whether or not laparoscopic surgery is acceptable in patients with clinical N2 colon cancer is unclear. Therefore, the present study aimed to evaluate the safety and oncological outcomes of laparoscopic surgery for clinical N2 colon cancer.

methodsThis retrospective study assessed a prospective database and identified 262 consecutive patients with clinical N2 colon cancer who underwent either laparoscopic or open primary resection between 2000 and 2016. After propensity-score matching, 162 patients were analyzed. The primary outcome of interest was the 3-year recurrence-free survival rate, and the secondary outcome of interest was the postoperative complication rate.

resultsThe 3-year recurrence-free survival rate did not differ markedly between the laparoscopic and open surgery groups (77.4% vs. 76.5%, p = 0.620). In addition, the incidence of postoperative complications did not differ markedly between the laparoscopic and open surgery groups (16.6% vs. 24.0%, p = 0.317).

conclusionsOur findings suggest that laparoscopic surgery is safe and effective for clinical N2 colon cancer. Laparoscopic resection can be considered in patients diagnosed with clinical N2 colon cancer.
