a Overall survival rate in the VATS group was significantly longer in comparison to the thoracotomy group. b Overall survival in the wound length ≤ 10 cm group was significantly longer than that in the wound length > 10 cm. c Overall survival in the operation time ≤ 248 min group was significantly longer than that in the operation time > 248 min group. d Overall survival in the preCRP ≤0.14 group was significantly longer than that in the preCRP > 0.14 group. e Overall survival in the postCRP ≤14.49 group was significantly longer than that in the postCRP > 14.49 group
