Predictive value of pain symptoms in correlation to
endometriosis involvement with the Receiver Operating Characteristic
curve
To test if endometriosis pain symptoms could predict deep endometriosis
involvement, we calculated receiver operating characteristic (ROC)
curves. The test in this case is the presence of endometriosis
classified with the Enzian (involvement yes or no), and the continuous
variable is the severity of symptoms measured with the NRS scale (0-10).
