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

objectivesTo better understand the relationship between angiotensinogen (AGT) genetic variation and essential hypertension, AGT genotypes and haplotypes were tested for association with hypertensive endophenotypes and essential hypertension.

methodsTwo hundred and fifty-six Hypertensive Pathotype (HyperPATH)/Specialized Center of Research (SCOR) cases and 126 controls were genotyped for 24 single-nucleotide polymorphisms (SNPs) in the AGT gene. SNPs and AGT haplotypes were tested for association with plasma AGT, renal plasma flow (RPF), and essential hypertension.

resultsNew associations between essential hypertension, plasma AGT, and RPF are reported for alleles -1178G, 6066A, 6152A, 6233C, and 12822C. The maximum odds ratio for association of hypertension and AGT genetic variation was 2.3 [95% confidence interval (CI) 1.5-3.8; P < 0.0003] for allele 6233C. Previous associations for -1074T, -532T, -217A, -6A, and 4072C are confirmed (P < 0.05). Sodium depletion enhances associations between AGT SNPs and plasma AGT. Most individually associated SNPs, including -6A and 4072C, are found on a common complete AGT haplotype, H4 (frequency = 0.09). Individuals with haplotype H4 have significantly higher plasma AGT and reduced RPF (P < 0.003 and P < 0.0002, respectively). Other common haplotypes are not associated with increased plasma AGT levels in this data set despite the presence of the -6A and 4072C alleles, suggesting that AGT haplotype H4 is more predictive of elevated plasma AGT than is -6A or 4072C.

conclusionThis study demonstrates the importance of analyzing haplotypes in addition to single genotypes in association studies. By demonstrating the dependence of AGT associations on sodium depletion status, it helps to explain previous conflicting association results.
