sPD‐1 was an indicator of initiating antiviral treatment in chronic hepatitis B (CHB). Patients in the CA group had higher serum sPD‐1 levels than did their counterparts in the CAN group (A). Receiver operating characteristic (ROC) curve for predicting CA group patients from CAN group patients (B). Among CHB patients with alanine aminotransferase (ALT) <2 ULN, those whose histology condition met the treatment criteria had higher serum sPD‐1 levels than did those who did not meet the criteria (C). ROC curve for predicting patients with ALT <2 ULN whose histology met the treatment criteria from those whose histology did not meet the treatment criteria (D)
