[Expression of PAH-DNA adducts in lung tissues of Xuanwei female lung cancer patients].
Article in Zhongguo fei ai za zhi = Chinese journal of lung cancer, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
BACKGROUND AND
objectiveThe coal-fired pollution in Xuanwei area has been considered to be local main reason for high incidence of female lung cancer. The aim of this study is to explore the expression of PAH-DNA adducts in lung tissues of Xuanwei female lung cancer patients and to explore the relationship between the large number of coal-fired pollution PAHs materials and the high incidence of Xuanwei female lung cancer.
methodsWe totally collected each 20 cases of Xuanwei female lung cancer patients, Xuanwei male lung cancer patients, Non-Xuanwei female lung cancer patients and collect each 10 cases of Xuanwei, Non-Xuanwei female patients with benign lung lesions. The cancer tissues, adjacent cancer tissues and normal lung tissues were collected in lung cancer patients and only the normal tissues were collected in benign lung lesion patients. There were total 80 cases and 200 tissues. Immunofluorescence was used to detect the expression of PAH-DNA adducts in each group. Image pro-plus 6.0 software was used to analyze the images and part quantified analysis. SPSS 13.0 statistical software was used to analyze the data.
resultsThe positive expression of PAH-DNA adducts in lung cancer tissues, adjacent cancer tissues and normal lung tissues of Xuanwei female lung cancer patients were 90%, 80% and 65%. They were higher than the positive expression of PAH-DNA adducts in Xuanwei male lung cancer patients (35%, 30%, 30%) and Non-Xuanwei female lung cancer patients (20%, 15%, 10%) (P < 0.01). The expressions in lung tissues ofXuanwei female benign lung lesion patients (positive expression is 70%) were higher than it in Non-Xuanwei female benign lung lesion patients (positive expression is 10%). With the direction changing from cancer tissues, adjacent cancer tissues to normal lung tissues, the expressions of PAH-DNA adducts were decreased but had no statistical difference (P > 0.05S).
conclusionThe expressions of PAH-DNA adducts in lung tissues of Xuanwei female were higher than which in Xuanwei male and Non-Xuanwei female.
