Abstract

At a center specializing in liver diseases, a new drug ("Tx. X") has been used to treat portal hypertension. The professionals are convinced that the drug reduces gastrointestinal bleeding associated with this syndrome. A statistical analysis shows that with Tx. X, there was a significant decrease in that complication, with p < 0.05.
