Note. lnTime.c is centered on a mean value of 4.37 (or ~79 days). Age.c is centered on a mean age of 58.16 years. Inpatient status was contrast coded as {−1 = no inpatient therapy/status uncertain; +1 = received inpatient therapy}.
*
denotes a 95% confidence interval that does not contain zero (i.e., p < 0.05). MOE = margin of error; Time = the number of days from the stroke to the beginning of outpatient therapy. For generating individual patient profiles, a non-centered version of this equation is also presented in the supplemental information.
