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

Genetic factors strongly influence interindividual variation in plasma high density lipoprotein cholesterol (HDL-C) levels, but the specific genetic polymorphisms that confer heritable variation in HDL-C levels have not been identified. In this study we examined the relationship between polymorphism in LIPC, the gene encoding hepatic lipase, and plasma HDL-C concentrations using a sequential approach comprising linkage analysis, DNA sequencing, and association studies. Linkage studies in 1465 American white subjects from 218 nuclear families indicated that allelic variation at, or closely linked to, the hepatic lipase gene accounts for a significant fraction ( approximately 25%) of the variation in plasma HDL-C concentrations. The hepatic lipase gene was then sequenced in selected individuals, and four novel polymorphisms were identified in the 5' flanking region of the gene. These polymorphisms were in complete linkage disequilibrium and thus identified a single novel allele. Association studies indicated that heterozygosity for the rare allele was associated with modestly increased concentrations of plasma HDL-C (41 +/- 11 vs. 37 +/- 10 mg/dl, P < 0.05) and apolipoprotein AI in men (131 +/- 23 vs. 122 +/- 21 mg/dl, P < 0.05) but not in women. Homozygosity for the rare allele was associated with markedly higher plasma HDL-C (63 +/- 3 mg/dl) and apolipoprotein AI (153 +/- 9 mg/dl) concentrations in men. The results of the association study were replicated in a second, independently ascertained sample. Taken together, the results of the linkage and association studies provide strong evidence that genetic variation in hepatic lipase activity is a major determinant of plasma HDL-C levels.
