Polymorphisms of promoter and coding regions of the arylamine N-acetyltransferase 2 (NAT2) gene in the Indonesian population: proposal for a new nomenclature.
Article in Journal of human genetics, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Polymorphisms of arylamine N-acetyltransferase 2 (NAT2) are reportedly associated with the risk of drug toxicities and development of various diseases. The present study examined NAT2 polymorphisms in both promoter and coding regions in the Indonesian population using PCR direct sequencing. The promoter and coding regions of NAT2 displayed 23 polymorphisms/variations, including eight new ones. Seven haplotypes in the promoter region and six haplotypes in the coding region were inferred. The haplotypes in promoter and coding regions showed limited combinations, and 13 combined haplotypes were inferred. The most frequent haplotypes were U1 (38.9%), U2 (33.5%) in the promoter region and NAT2*4 (37.3%), NAT2*6A (36.8%) in the coding region. When converted to predicted phenotypes, the studied population comprised 65.4% rapid acetylators and 35.6% slow acetylators according to bimodal distribution. According to trimodal distribution, frequencies of predicted phenotypes were 13.6, 50.8 and 35.6% for rapid, intermediate and slow acetylators, respectively. Frequencies of NAT2 alleles for the Indonesian population resembled those of other Southeast Asian populations. We also propose a new NAT2 nomenclature composed of haplotypes in the promoter region and conventional NAT2 haplotypes in the coding region, symbolized by NAT2*4.U1, NAT2*4.U2, NAT2*4.U3, NAT2*4.U5, NAT2*4.U6, NAT2*4.U7, NAT2*6A.U1, NAT2*7B.U2, NAT2*7B.U3, NAT2*5B.U1, NAT2*5B.U4, NAT2*12A.U4 and NAT2*13.U1.
