The vertical axis displays the number of patients, from zero to one hundred and fifty. The horizontal axis displays the number of biopsies per year, from zero to less-than or equal to six. The frequency of EMBs was reduced from 3.0 EMBs per year in the EMB arm to 0.5 in the GEP arm. P is less than zero-point-zero-zero-one percent.
