Rivalta Test The Rivalta test was used in order to differentiate a transudate from an exudate. A positive the test meant high protein concentration of ascite fluid and possibly a relationship with Spontaneous bacterial peritonitis (SBP)

Ascites LDH Ascites lactate dehydrogenase was used to differentiate malignant transudate from benign transudate

^aGI group: The gastrointestinal group included hepatic cancer, pancreatic cancer, colorectal cancer and etc

^bOther primary tumors included lung, breast, renal, etc. Unknown is for patients that had malignant proof but not primary proof
