Notes:
*
P-value for completers vs non-completers was determined using the Fisher exact test.
†
Information was available for 331 patients in the overall population (completers, n=119; non-completers, n=212).
‡
Information was available for 330 patients in the overall population (completers, n=119; non-completers, n=211).
