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

backgroundLaparoscopic surgery has achieved significant results in elderly patients with colorectal cancer (CRC). In this study, we compared the short-term and long-term outcomes of open surgery and laparoscopic surgery in patients with CRC aged above 75 years at a single tertiary medical center.

methodsWe analyzed 967 patients who underwent curative resection for primary colorectal adenocarcinoma without distant metastasis between January 2009 and December 2015, in a single institution. Of the enrolled patients, 305 underwent laparoscopic surgery, and 662 received open laparotomy surgery.

resultsCompared to the patients who underwent open surgery, those who received laparoscopic surgery had significantly shorter postoperative stay (10.3 vs. 13.5 days p < 0.001) and similar postoperative morbidity (p = 0.354) and mortality (p = 0.082). In the laparoscopy cohort, six of 305 patients were converted to open surgery and one died. The long-term overall survival, cancer-specific survival, and recurrence rate were similar between both cohorts in each stage.

conclusionsLaparoscopic surgery is suitable for elderly patients owing to shorter postoperative stay, similar long-term outcomes with open surgery, and acceptable low conversion rates. For long-term overall and oncological outcomes, the results of laparoscopic surgery were similar to that of open surgery in each TNM stage.
