a
For community stays and nursing home stays, the observational window was within 90 d discharge of the index hospitalization. The HIH period was considered as community days. For control patients, we did not include those discharged to death.
b
Data are for 286 control patients vs 94 enrollees after matching.
c
Data are for 297 control patients vs 98 enrollees after matching.
