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

Previously we presented suggestive evidence from an F2 segregating population for an interaction on blood pressure (BP) between quantitative trait loci (QTL) on rat chromosomes (Chr) 2 and 10. To prove the existence of such an interaction, we developed congenic strains for Chr 2 and 10 by introgressing the low BP QTL alleles into the Dahl salt-sensitive (S) strain. A double congenic strain was also constructed with both the Chr 2 and 10 low BP QTL alleles on the S background. The four strains (S, Chr 2 congenic, Chr 10 congenic, and Chr 2/10 double congenic) were studied for BP response to increased salt intake. An analysis of variance showed significant main effects of Chr 2, Chr 10, and a significant interaction between Chr 2 and 10 on BP and heart weight (all P < 0.0001). The interaction accounted for 24 mmHg of BP and 79 mg of heart weight. Thus, the discovery and proof of epistatic interactions are clearly critical to understanding the genetics of blood pressure.
