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

aimThe aim of this study is to compare pathological findings in rectal cancer specimens obtained by laparoscopy or laparotomy. MATERIALS AND

methodsBowel length, distal and circumferential margins, and number of total and positive nodes harvested were prospectively recorded in specimens obtained from 100 consecutive patients who had a laparoscopic total mesorectal excision for cancer. These data were compared with those extracted from a well-matched group of 100 patients who had an open procedure.

resultsThe mean length of the specimens was 31.04 cm in the case group and 29.45 cm in the control group (not significant (NS)). All distal margins in both groups were negative. The circumferential margin was positive in four cases in the case group and nine cases in the control group (NS). The mean number of lymph nodes harvested was 13.76 nodes/patient in the case group and 12.74 nodes/patient in the control group (NS). The mean number of involved lymph nodes was 1.18 node/case in the case group and 1.96 node/case in group 2 (NS).

conclusionThere is no difference between laparoscopic or open approaches concerning specimen's length, distal margin, circumferential margin, and total and positive lymph nodes. Laparoscopic rectal resection is not only technically feasible but it seems also oncologically safe.
