During the study , logUPC ( geometric mean ( 95 % CI ) and SBP ( meanSD mmHg ) significantly decreased ( paired t-test , P = 0.001 ) in Group-RD ( logUPC ( D0 ) = 3.16 [ 1.9-5 .25 ] ; UPC ( D60 ) = 1.20 [ 0.59-2 .45 ] ; SBP ( D0 ) = 160 17.2 ; SBP ( D60 ) = 151 15.8 ) , but not in Group-MD ( UPC ( D0 ) = 3.63 [ 2.69-4 .9 ] ; UPC ( D60 ) = 2.14 [ 0.76-6 .17 ] ; SBP ( D0 ) = 158 14.7 ; SBP ( D60 ) = 153 11.5 ) .
