Measures included mean daily utilization via processor datalogging and Consonant\u2010Nucleus\u2010Consonant (CNC) word recognition at 1, 3, 6, and 12 months postactivation; distribution of utilization categories; multivariable predictors of limited use; and cross\u2010temporal predictive validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      SSD showed lower utilization than BSHL through 6 months postactivation, with near\u2010convergence by 12 months.
