Table 3 Akaike Information Criterion (AIC) values for the Cox models, Beyond the first 6 months of follow-up (370 patients)

From: Evaluation of RECIST in chemotherapy-treated lung cancer: the Pharmacogenoscan Study

Model   HR (95% CI) p value AIC*
RECIST Partial response 1   1835.264
  Stable disease 1.19 (0.90-1.58) 0.22  
  Progressive disease 3.12 (1.89-5.14) <10−4  
UCSTS per 10% difference 1.07 (1.03-1.11) <10−4 1835.312
  1. The analysis was routinely adjusted on histology and cancer spread. Sex and chemotherapy doublet were proposed to the model but not kept at the final step. The analysis was stratified on ECOG-PS and hospital.
  2. *In the model with RECIST, −2log likelihood = 1823.264 with 6 degrees of freedom.In the model with UCSTS, −2log likelihood = 1825.312 with 5 degrees of freedom.
  3. p = 0.15.
  4. HR, hazard ratio; 95% CI, 95% confidence interval; RECIST, Response Evaluation Criteria in Solid Tumors; UCSTS, unidimensional continuous-scale tumour size.
