RECRUITMENT
A survey was administered during the planning phase of the protocol to identify possible recruiting centers and estimate the number of patients that each center could possibly enroll in the study period. Thereafter, the list of the participating centers was redacted and proposed. In case a problem of low recruitment is encountered, any center with a consistently low recruitment rate will be contacted to address site-specific issues. If necessary, new investigators and sites will be added to overcome low recruitment rates.
