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

backgroundAs the population ages, the number of elderly patients with colorectal cancer is increasing year by year. However, older people have rarely been the focus of studies on colorectal cancer. Therefore, in the present study, we aimed to carry out a retrospective analysis of this patient subgroup.

methodsA retrospective study of clinical data of patients aged over 80 years who died from colorectal cancer in our hospital between 1993 and 2020 was performed. Logistic regression, the Kaplan-Meier method, and a multivariate Cox proportional hazards model were used to analyze the overall survival and treatment outcomes of the patients.

resultsA total of 87 patients were included in the study. The overall median survival was 45 months. In most patients, the primary lesion was located in the right colon. One-quarter of the patients refused to accept any treatment. Patients with stage IV tumors, who accounted for the largest proportion of the study population, displayed a higher rate of abandoning treatment than did patients of other stages. Almost all patients with stages II and III accepted surgery. Patients who underwent surgery to treat their colorectal cancer had longer survival than those who did not.

conclusionsOld age should not be a reason for giving up treatment for colorectal cancer. The treatment of colorectal cancer patients aged 80 years and above requires individualized evaluation and more aggressive treatment to achieve greater benefits.
