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

purposesTo establish the safety of laparoscopic-assisted colorectal resection for colorectal cancer in elderly patients aged ≥80 years.

methodsData were obtained from a chart review of patients who underwent colorectal cancer resection between 2009 and 2014 in Kochi Medical School. The effect of patient age on the extent of lymph node dissection and operative safety was assessed by comparing the short-term results of elderly patients with those of younger patients after propensity score matching.

resultsOf a total of 506 patients with colorectal cancer, 398 underwent laparoscopic surgery and 23% of these patients were aged ≥80 years old. The elderly patients tended to have poorer general condition and larger tumors, although no significant differences were found in tumor invasion, lymph node metastasis, or synchronous distant metastasis between the groups. After adjustment for preoperative factors, we noted that the elderly patients tended to undergo less aggressive surgical resection (P = 0.01). Further analysis after including surgical factors for propensity score matching revealed a similar rate of complications in the two groups (24 vs. 25%, respectively; P = 0.85), and similar postoperative death rates and length of postoperative hospital stay.

conclusionThe findings of the present study demonstrate that laparoscopic surgery for colorectal cancer should not be avoided based on simply the age of the patient.
