The original article [1] contains numerical errors in the following sentence regarding median irOS:

‘Additionally, CLDN18.2-positive group had shorter OS and irOS than CLDN18.2-negative group (median OS: 23.33 vs.36.6 months, P < 0.001; median irOS: 10.03 vs. 20.13 months, P = 0.044, respectively).’

The sentence should instead read as follows:

‘Additionally, CLDN18.2-positive group had shorter OS and irOS than CLDN18.2-negative group (median OS: 23.33 vs.36.6 months, P < 0.001; median irOS: 9.27 vs. 12.83 months, P = 0.044, respectively).’'
