Correction: Working to Increase Stability through Exercise (WISE): screening, recruitment, and baseline characteristics (Trials, (2021), 22, 1, (809), 10.1186/s13063-021-05761-0)

Following the publication of the original article [1], we were notified that Tables 4 and 5 each need to have a footnote at the bottom to address missing data. Under Table 4 the footnote should read: "Due to missing data, which differed for each variable, group sizes (N) ranged as follows: Overall (1038- 1139); Control (512-569); Intervention (526-570). Under Table 5 the footnote should read: "Due to missing data, which differed for each variable, group sizes (N) ranged as follows: Overall (1038-1139); Penn State (443-501); Pitt (487-526); Temple (108-112)". Proposed sample size was 2100, not 2000 as was noted on page 3. This change was made between the funding announcement and the beginning of recruitment, to provide additional power to detect proposed differences. The original article has been corrected.
