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 effects of laparoscopic colorectal surgery (LAC) on the long-term outcomes of elderly patients remain unclear. This study aimed to assess the short- and long-term outcomes of LAC in elderly colorectal cancer patients and to quantify the effects of LAC on the patient death patterns.

methodsThe clinicopathological data of elderly colorectal cancer patients aged ≥80 years old who were treated between 2006 and 2014 were extracted. The relationships between the clinicopathological factors and overall survival (OS) were assessed using the Cox proportional hazards model and Kaplan-Meier analyses. The risk factors for the types of death were estimated using a competing risk analysis.

resultsA total of 107 patients were included. Fifty-two patients underwent LAC, whereas 55 underwent open surgery (OC). There were no significant differences in the American Society of Anesthesiologists grade or comorbidity rate between the groups. The postoperative complication rate was significantly lower with LAC than OC (p < 0.001). After adjustment for covariates, laparoscopic surgery was not a significant risk factor for any of the types of death.

conclusionsLAC is an effective and safe technique for elderly patients with colorectal cancer. Furthermore, there was no significant association between the surgical procedure and the pattern of death.
