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

4,4'-oxydianiline (ODA) is an environmental aromatic amine reasonably anticipated to be a human carcinogen. We investigated ODA genotoxicity and oxidative stress modified by N-acetyltransferase 2 (NAT2) genetic polymorphism in yeast and DNA repair deficient (UV5) Chinese hamster ovary cells (CHO) expressing human NAT2*4 (rapid acetylator allele) or human NAT2*5B (slow acetylator allele) and in cryopreserved human hepatocytes from rapid, intermediate, or slow NAT2 acetylator genotypes. N-acetylation of ODA was both concentration- and time-dependent and significantly higher in yeast and CHO cells expressing NAT2*4 versus NAT2*5B. ODA-induced DNA damage response and reactive oxygen species (ROS/RNS) were significantly higher, while intracellular reduced glutathione (GSH) and oxidized glutathione (GSSG) ratio or mitochondrial integrity were significantly lower in CHO cells expressing NAT2*4 than NAT2*5B. Dose- and NAT2 phenotype-dependent responses also were observed in human cryopreserved human hepatocytes. Our findings have important implications for precise risk assessments following exposures to ODA and azo dye precursors.
