Ratio

The division of one piece of financial information by another. Financial ratios are very common in fundamental analysis, which investigates the financial health of companies. An example of a financial ratio is the price-earnings ratio, which divides a publicly-traded company's share price by its earnings per share. This and other ratios help analysts determine whether a company's share price properly reflects its performance.

ratio

The relation between two quantities when compared mathematically with one another. For example, the most frequently used ratio among investors is the price-earnings ratio. Financial analysts, investors, and managers use ratios to evaluate many factors such as the attractiveness of a stock or the operating efficiency of a company. Also called financial ratio. See also activity ratio, debt management ratio, liquidity ratio, profitability ratio.

After adjustment for confounding factors (gender, age, diabetes mellitus, and smoking), serum miR-126 expression levels were positively correlated with LVEF, and negatively correlated with the logarithm of NT-proBNP and the cardiothoracic ratio (all P<0.05, Table 6).
Another important finding in our study was that patients in the AF, HF, and HF-AF groups had higher NT-proBNP levels, a lower LVEF, a larger LA diameter, and a higher cardiothoracic ratio than the controls.
Moreover, serum miR126 levels are closely correlated with heart function indices, including NT-proBNP levels, LVEF, LA diameter, and the cardiothoracic ratio. However, the potential limitations of the use of U6 snRNA as an endogenous reference may have affected detection of plasma miRNA expression.
Although the preoperative chest radiographs showed that all patients had increased cardiothoracic ratio, postoperative chest radiographs showed significant improvements in pulmonary vascularity and reduction in the size of cardiac contour.

Among 25 patients with severe mitral regurgitation, cardiothoracic ratio was normal in 20 (80%) patients whereas cardiac enlargement was documented in 17 (68%) patients on echocardiography.
One of the methods used to quantify the heart size on chest radiography is the cardiothoracic ratio (1).
