ATPase may play a critical role in disturbance of energy metabolism in congestive heart failure rats.

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
objectiveThis study aims to explore the expression and significance of ATPase in myocardium of congestive heart failure induced by pressure overload in rats.
methodsMale SD rats were divided into 3 groups randomly: Control group (C group), coarctation of abdominal aorta 15 weeks group (A group) and sham operation group (SH group). The hemodynamics parameters were measured. The size of adenine acid pool (ATP, ADP) in myocardium was measured by high performance liquid chromatography (HPLC). The mRNA copies of ATPase-α subunit, ATPase-6 subunit in ventricular myocardium were determined by RT-PCR. The protein content of F1-ATPase in mitochondria was detected by Western blot analysis.
resultsThe ±dp/dtmax and contents of ATP and ADP decreased significantly in myocardium were decreased in A group. Compared with C and SH group, the mRNA copies of ATPase-α subunit, ATPase-6 subunit and the protein content of F1-ATPase were decreased in A group.
conclusionThe expression of F1-ATPase decreased parallel with abnormal of the adenine nucleotide in myocardium of congestive heart failure. It may play a critical role in disturbance of energy metabolism in disfunction of heart.
