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
To investigate the K-ras genetic mutation status in colorectal cancer patients, compare the difference of K-ras genetic mutation rate in Han and Uygur nationality and analyze the influencing factor. 91 cases (52 cases of Han nationality and 39 cases of Uygur nationality) of colorectal biopsy or surgical ablation pathology specimen from the first affiliated hospital of Xinjiang Medical University during January, 2010 to March, 2013 were collected to detect the 12th and 13th code mutation status of K-ras gene exon 2 with pyrosequencing method and compare the difference of K-ras gene mutation rate between Han and Uygur nationality patients. Single factor analysis and multiple factor logistic regression analysis were utilized to analyze the influencing factor for K-ras genetic mutation. 33 cases of patients with K-ras genetic mutation were found from the 91 cases colorectal cancer patients and the total mutation rate was 36.3%. Among them, 24 cases (72.7%) were found with mutation only in the 12th code, 9 cases (27.3%) were found with mutation only in the 13th code and no one case was found with mutation in both the two codes. Mutation rate of the 12th code in the Uygur nationality was significantly higher than that in the Han nationality (P<0.05), but there were no significant difference in the comparison of the total mutation rate and the 13th code mutation rate between the two groups (P>0.05). There were no associativity (P>0.05) between the K-ras genetic mutation and sex, age, smoking history, drinking history, tumor location, macropathology type, differentiation level, staging, invasive depth, lymph nodes transferring and metastasis in colorectal cancer patients (P>0.05). K-ras genetic mutation rate is high in colorectal cancer patients. The mutation rate of 12th code in Uygur nationality is higher than that in Han nationality. There is no significant associativity between K-ras genetic mutation rate and patients' clinical pathology characteristic.
