Cardiac myosin phenotype remodeling following chronic spinal transection.

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.
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
Spinal transection results in profound neural and functional changes of the heart. However, phenotypic alterations in cardiac myosin heavy chains (MyHC) as a result of spinal transection have not been explored. Hearts were removed from 180 day old rats who had their spinal cords transected between T6 and T9 (ST; n = 10) and intact controls (IN; n = 9). Myosin was isolated from the left and right ventricles and separated into its respective heavy chain components (designated as alpha and beta) by SDS-PAGE. The resulting gels were scanned with a laser scanning densitometer to obtain relative concentrations of these two heavy chains. The left ventricles of the ST rats had a significantly higher (p < 0.05) alpha to beta ratio (10.89) than the intact controls (4.20), while the right ventricle of the ST rats had a significantly lower (p < 0.05) alpha to beta ratio (7.49) relative to intact controls (13.62). The left and right ventricular weight to body weight ratios were not different in ST compared to IN. Additionally, there were significant within group differences (p < 0.05) between the alpha and beta MyHC ratios for the left and right ventricles. These data suggest that 1) spinal transection causes remodeling of the right and left ventricles and 2) the two ventricles do not remodel as a unit.
