From: Clinically important deep vein thrombosis in the intensive care unit: a survey of intensivists
Ultrasonographic factors considered by respondents to make a deep venous thrombosis (DVT) clinically important in the intensive care unit setting. The scale used was as follows: 1 = much less likely to make the DVT clinically important; 2 = somewhat less likely to make the DVT clinically important; 3 = neither more nor less likely to make the DVT clinically important; 4 = somewhat more likely to make the DVT clinically important; and 5 = much more likely to make the DVT clinically important.
