Eight years post-randomization , individuals randomized to ILI had better SPPBexp scores -LSB- adjusted mean ( SE ) difference : @ ( @ ) , P = @ -RSB- and faster @-m and @-m walk speeds -LSB- @ ( @ ) m s ( -@ ) , P = @ , and @ ( @ ) m s ( -@ ) , P = @ , respectively -RSB- compared to those randomized to DSE .
