Effects of gender difference on cardiac myocyte dysfunction in streptozotocin-induced diabetic 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
The main characteristics of type 1 diabetic cardiomyopathy include depressed contractility and altered electrophysiological properties in ventricular myocytes. The goal of the present study was to determine the potential influence of gender in the diabetes-induced pathogenesis of ventricular myocyte function. Diabetes in both male and female rats was induced by a single intravenous injection of streptozotocin (STZ). Diabetic rats exhibited hyperglycemia and reduced body weight gain in both male and female groups. Neither contractile profiles nor activity of three types of K+ channels of ventricular myocytes was significantly different between nondiabetic male and female rats. Ventricular myocytes isolated from diabetic rats exhibited significant depression in cell contraction and relaxation, which was associated with depression of intracellular Ca2+ ([Ca2+]i) transient. The degrees of contractile depression were comparable in ventricular myocytes obtained from both male and female diabetic rats. Similarly, diabetes depressed three types of outward K+ currents (Ito, Ik, and Iss) to the same extent in both gender myocytes. These data demonstrate that in this animal model of diabetes, gender difference in cardiac myocyte functions was eliminated.
