At baseline , interleukin-@ was independently associated with mortality , whereas both interleukin-@ levels ( hazard ratio = @ -LSB- @-@ @ -RSB- ; p = @ ) and procalcitonin levels ( hazard ratio = @ -LSB- @-@ @ -RSB- ; p = @ ) @ hours after out-of-hospital cardiac arrest were associated with @-day mortality with no interactions between targeted temperature management group and levels of interleukin-@ ( p = @ ) or procalcitonin ( p = @ ) .
