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

rationaleSeverity of tissue injury in occlusive disease is dependent on the extent (number and diameter) of collateral vessels, which varies widely among healthy mice and humans. However, the causative genetic elements are unknown. Recently, much of the variation among different mouse strains, including C57Bl/6J (B6, high extent) and BALB/cByJ (Bc, low extent), was linked to a quantitative trait locus on chromosome 7 (Candq1).

objectiveWe used congenic mapping to refine Candq1 and its candidate genes to create an isogenic strain set with large differences in collateral extent to assess their impact and the impact of Candq1, alone, on ischemic injury. METHODS AND

resultsSix congenic strains possessing portions of Candq1 introgressed from B6 into Bc were generated and phenotyped. Candq1 was refined from 27 to 0.737 Mb with full retention of effect, that is, return or rescue of phenotypes from the poor values in Bc to nearly those of wild-type B6 in the B6/B6 congenic mice as follows: 83% rescue of low pial collateral extent and 4.5-fold increase in blood flow and 85% reduction of infarct volume after middle cerebral artery occlusion; 54% rescue of low skeletal muscle collaterals and augmented recovery of perfusion (83%) and function after femoral artery ligation. Gene deletion and in silico analysis further delineated the candidate genes.

conclusionsWe have significantly refined Candq1 (now designated determinant of collateral extent 1; Dce1), demonstrated that genetic background-dependent variation in collaterals is a major factor underlying differences in ischemic tissue injury, and generated a congenic strain set with wide allele dose-dependent variation in collateral extent for use in investigations of the collateral circulation.
