The CN group received more community health services ( rate ratio , 1.94 ; 95 % CI , 1.35-2 .81 ; P < 0.001 ) than participants receiving standard care ; however , this did not result in statistically significant differences in number of re-presentations ( rate ratio , 0.83 ; 95 % CI , 0.68-1 .01 ; P = 0.07 ) , number of readmissions ( rate ratio , 0.85 ; 95 % CI , 0.70-1 .04 ; P = 0.11 ) , quality of life at 24 months ( mean difference , 0 ; 95 % CI , -0.10 to 0.09 , P = 0.93 ) , or other measures .
