EQ-@D utility scores averaged @ ( @ % CI @-@ ; p = @ ) better with levodopa than with levodopa-sparing therapy ; rates of dementia ( hazard ratio -LSB- HR -RSB- @ , @ % CI @-@ , p = @ ) , admissions to institutions ( @ , @-@ ; p = @ ) , and death ( @ , @-@ , p = @ ) were not significantly different , but the upper CIs precluded any substantial increase with levodopa compared with levodopa-sparing therapy .
