Randomization
Eligible patients were randomly allocated in a 1:1 ratio to ICLIT or SCIT group. With random-number tables, we selected 50 random numbers in sequence starting from any random number and put them in numerical order. Numbers 1-25 and 26-50 were divided into ICLIT group and SCIT group, respectively. The randomization was conducted using SPSS, Version 27.0 (SPSS Inc., Chicago, IL, USA).
