^aCox regression model, with age at CRC diagnosis as entry time and age at death or censoring as exit time, stratified by country and adjusted for year of CRC diagnosis, tumor stage, tumor grade, tumor site, sex, educational level, smoking status, plus the component that has been removed from the score. ^bIn women only.
