Errors in Table

In the Original Investigation titled “Examining Bias in Studies of Statin Treatment and Survival in Patients With Cancer,”¹ published online on August 20, 2017, in JAMA Oncology, Table 1 contained the following errors: (1) the category descriptions were not all accurate; (2) the studies listed in the table were not all correctly categorized; (3) a study included in category 1 did not meet study eligibility criteria and should not have appeared in the table; and (4) resulting data errors were present in several places in the table and in a few places in text. None of these errors weakened the study conclusions; in fact, data now reported in corrected Table 1 strengthen the concordance between the reviewed literature and the study findings. This article has been corrected online.
