In the supplemental data for the article beginning on page 2068 in the 26 March 2015 issue, the legend to Table S2 read, “The ADL scale includes six items (bathing, dressing, toileting, transferring, continence, and feeding), with a score for each item ranging from 0 (able to perform the activity) to 1 (unable to perform the activity). Total score ranges from 0 to 6. The IADL scale includes eight items (ability to use the telephone, shopping, cooking, housekeeping, doing laundry, taking own medication, making transports, and to handle finances), with a score for each item of 0 (high function, independent) or 1 (low function, dependent). The total score ranges from 0 to 8.” The legend should read, “The ADL scale includes six items (bathing, dressing, toileting, transferring, continence, and feeding), with a score for each item ranging from 0 (unable to perform the activity) to 1 (able to perform the activity). Total score ranges from 0 to 6 (0 = completely dependent; 6 = completely independent). The IADL scale includes eight items (ability to use the telephone, shopping, cooking, housekeeping, doing laundry, taking own medication, using transportation, and handling finances), with a score for each item of 0 (low function, dependent) or 1 (high function, independent). The total score ranges from 0 to 8 (0 = completely dependent; 8 = completely independent).” The error has been corrected in the online data supplement.
