  1. Within each model, variables are ranked by descending importance as expressed by their absolute standardized regression coefficients. Histology was encoded as “0” for serous and “1” for non-serous; Peritoneal carcinomatosis was encoded as “0” for no and “1” for yes; Grading was encoded as “0” for Grade 1 and 2 and “1” for Grade 3; Residual disease was encoded as “0” for no and “1” for yes; beta, regression coefficient (log hazard ratio); HR, hazard ratio; STDBETA, standardized regression coefficients. By multivariate modeling with penalized likelihood, the multivariate-adjusted HR shows the direction and magnitude of prognostic effect if adjusted for other variables. Ridge regression shifts the HR towards the value of 1.0 to avoid overestimation bias and to decrease variance in models with many variables
