ST, speech-language-hearing therapy; OT, occupational therapy; PT, physical therapy; JCS, Japan Coma Scale; FIM, functional independence measure; OR, odds ratio; CI, confidence interval.
Adjustment for age, sex, hospital, hospitalization year, dementia level at hospitalization, JCS score at hospitalization, FIM walk/wheelchair score at hospitalization, FIM comprehension at hospitalization, number of days spent in hospital, and side with more severe paralysis. Further adjustment for OT and PT in the analysis of ST, ST and PT in the analysis of OT, and OT and ST in the analysis of PT. Each OR represents the comparison between long and short therapy duration, with the OR for short duration always being reference.
