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

backgroundHepatoma is caused by many factors including alcohol, chemicals, viral infection, and chronic inflammation. Cytochrome P450 polymorphism plays an important role in its pathogenesis. CYP2D6, CYP2E1, and CYP1A1 have been identified to be related with hepatic carcinogenesis and tumor size and stage. However, no studies have been performed on CYP2C9, a major CYP in the liver and hepatoma. AIM OF THE STUDY: To identify if there is polymorphism of CYP2C9 in a HepG2 cell line.

methodsA pair of primers was used to clone CYP2C9 exon 3 region and subsequently sequenced. The sequence was compared to normal CYP2C9 for identification of any mutation.

resultsA point mutation was identified. It was located in the amino acid number 144 of CYP2C9 protein with the change of normal amino acid arginine into cysteine, which is the same as identified in poor metabolism patients as homozygous CYP2C9*2.

conclusionsThere is a mutation (CYP2C9*2/ CYP2C9*2) in a HepG2 cell line. Thus, polymorphism of CYP2C9 may also be involved in the carcinogenesis of hepatoma as CYPs2D6 and 2E1.
