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 aim of this study was to compare the outcomes of laparoscopic surgery with those of open resection in patients with extraperitoneal rectal cancer.

methodsFive hundred forty-four patients with extraperitoneal rectal cancer who underwent curative resection between 1996 and 2007 were included. Patients were divided into a laparoscopic surgery group (LAP, n = 170) and an open surgery group (OPEN, n = 374).

resultsMorbidity requiring surgical correction was 5.8% in the LAP group and 4.8% in the OPEN group (p = 0.75). The anastomotic leakage rate was similar in both groups (5.7% in both; p = 0.98). Differences were found in preoperative carcinoembryonic antigen (CEA) (LAP group 4.6 ng/ml, OPEN group 7.7 ng/ml, p = 0.001), sphincter preservation (LAP group 82.9%, OPEN group 69.8%, p = 0.001), and mean distance from anal verge (LAP group 4.6 cm, OPEN group 5.2 cm, p = 0.002). Local recurrence and metastasis were similar by stage.

conclusionsThe results of this study show that laparoscopic resection of extraperitoneal rectal cancer was safe and effective.
