Association between age and synchronous liver metastasis in female colorectal cancer patients.

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.
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 purpose of this study is to investigate the relationship between age and synchronous liver metastasis in female colorectal cancer patients.
methodClinical and pathological data from 655 consecutive female patients who were treated in Qilu Hospital from January 2000 to January 2010 were reviewed. First, the patients were divided into two groups: 60 years or younger and 61 years or older. A chi-square test was adopted to analyse the difference in clinicopathological characteristics between the two groups. Then, they were classified into two groups according to liver metastasis. Univariate analysis and logistic multivariate regression analysis were adopted to discriminate risk factors of liver metastasis.
resultsThe chi-square test demonstrated that significant difference existed between the younger and the older groups in terms of liver metastasis (P < 0.001), lymph node metastasis (P < 0.001), tumour localization (P < 0.001), tumour invasion depth (P < 0.001), type of tumour (P < 0.001), tumour cell differentiation (P < 0.001) and venous invasion (P < 0.001). Univariate analysis demonstrated that seven factors are associated with liver metastasis. Logistic regression analysis indicated that age (P = 0.005), tumour size (P < 0.001), tumour invasion depth (P = 0.001), tumour cell differentiation (P = 0.029) and type of tumour (P < 0.001) are independent risk factors of liver metastasis.
conclusionsThe liver metastatic potential of colorectal cancer may be different between younger and older female patients. Age may independently influence liver metastasis in female colorectal cancer patients.
