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

To investigate mechanisms causing p53 mutations in lung cancer cases, relations between p53 gene mutations and aetiological factors such as smoking history or family history of cancers cases. The contribution of genotypes related to carcinogen metabolism (CYP1A1 and GSTM1) was also analysed. p53 mutations were observed in 13 cases (37.5%). Seven (53.8%) of the 13 patients with p53 mutation compared with five (22.7%) of 22 patients without had a family history of cancer. However, there was no significant relation between p53 mutation or family history of cancer and CYP1A1 or GSTM1 genotypes. In conclusion, p53 mutation might be associated with the inherited characteristics that result in familial aggregation of lung cancer; however, this association was not explained by genotypes of enzymes related to carcinogen metabolisms.
