Errors in Table

In the Original Investigation titled "Examining Bias in Studies of Statin Treatment and Survival in Patients With Cancer," 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.
