From: A prediction model using 2-propanol and 2-butanone in urine distinguishes breast cancer
Box charts of the peak areas of the 2-butanone and 2-propanol of the external validation set using the model. Box plots of the peak areas of 2-propanol and 2-butanone in the external validation set using the model. The peak areas in the external validation set were similar to those in the training set. (A) Peak areas of 2-butanone and (B) 2-propanol. BCP breast cancer patient, HC healthy control.
