CR, complete response; OS, overall survival; PD, progression of disease; PFS, progression free survival; PR, partial response; SD, stable disease; —, The data were not described clearly; →, It means a change from the former one to the latter one.
This study did not mention whether AIs were used as first‐line therapy or as second‐line therapy.
