Correction: Adjusted Age-Adjusted Charlson Comorbidity Index Score as a Risk Measure of Perioperative Mortality before Cancer Surgery

The phrase “hazard ratios” appears incorrectly throughout the article. The correct phrase should be “odds ratios.”

In Table 2, the column headings “Adjusted HR” should be “Adjusted OR”. Please see the corrected Table 2 here.
