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

Inter-individual variability in drug response is well known. Genetic polymorphism in genes encoding drug-metabolizing enzymes results in variation in drug metabolism and in turn drug response. The cytochrome P450 enzymes (CYP) play a central role in the metabolism of many therapeutic agents. CYP2C19 gene polymorphism is widely studied in Caucasians, African, and Oriental populations; however, far less is known about other ethnic groups such as Indians. Indian population is an inter-mixture of the Aryan, Dravidian, Kolarain, and the Mongoloid races. CYP2C19 gene polymorphism is reported in North Indian and South Indian populations yet not much is known about Maharashtrian population of Australoid-Europoid origin residing in Western India. This is the first report on CYP2C19 allele and genotype frequencies in Maharashtrian population. In this study, genotypes of major allelic variants of CYP2C19 gene in 139 unrelated healthy Maharashtrian subjects was determined and their frequencies were compared with previously studied Indian and other populations. Meta-analysis revealed that the study population is distinct from Caucasians, Africans and some of the Asian populations and significant heterogeneity exists among Indian subpopulations.
