These did not affect prevalence of low ( < 0.90 ) ABI ( 3.60 % in DSE versus 3.14 % in ILI ; P = 0.20 ) or elevated ( > 1.40 ) ABI ( 7.52 % in DSE versus 7.59 % in ILI : P = 0.90 ) , but produced smaller mean ( SE ) maximum interartery systolic blood pressure differences among ankle sites [ 19.7 ( 0.2 ) mmHg for ILI versus 20.6 ( 0.2 ) mmHg for DSE ( P < 0.001 ) ] and between arms [ 5.8 ( 0.1 ) mmHg for ILI versus 6.1 ( 0.1 ) mmHg for DSE ( P = 0.01 ) ] .
