A classification tree predicting patients with small PA lesions for a serum K threshold of 2.82 mEq/L. The threshold for serum K was assessed by CHAID analysis. “Large” and “Small” indicate patient groups with large and small PA lesions, respectively. Numbers without and with parentheses within each node indicate the number and percentage of patients, respectively. The upper node was separated from the lower nodes based on the serum K value (≤2.82 mEq/L vs. >2.82 mEq/L). The p value was calculated by Fisher’s exact test
