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
objective8-hydroxygumine DNA glycosylase 1 (OGG1) is a DNA repair enzyme, which can repair damaged DNA by excising 8-dihydro-8-oxoguanine (8-OH-G). Polymorphisms in human OGG1 gene (hOGG1) may alter glycosylase activity, thereby affects its repair to the damaged DNA, resulting in contribution to carcinogenesis. However, an association of genetic variants of hOGG1 promoter with non-small cell lung cancer (NSCLC) remains unclear. The present study aims to explore whether there are mutations in the promoter region of hOGG1 and the association of the potential genetic variants with NSCLC.
methodsForty lung cancer patients were enrolled from January, 2003 to December, 2005 in the first affiliated hospital of Soochow University. PCR-SSCP followed by direct sequencing were performed to detect mutations within the promoter region of the hOGG1 gene in NSCLC and corresponding paracancerous lung tissues.
resultsNo abnormal mutation was found in the promoter region of the hOGG1 gene in 40 patients with NSCLC. However, a SNP rs159153 in hOGG1 was significantly associated with higher TNM stage (P=0.008). Moreover, lower frequency of lymph node metastasis was observed in smoker patients with NSCLC (P=0.034).
conclusionsThe SNP rs159153 in the promoter region of the hOGG1 gene and smoking history may effectively forebode the aggressiveness and metastatic potential of NSCLC.
