In a linear model , hazard ratios for death were @ ( @ % confidence interval , @-@ @ ) for increased clot formation speed , @ ( @-@ @ ) for decreased angle , @ ( @-@ @ ) for decreased clot strength and @ ( @-@ @ ) for decreased fibrinogen contribution to clot strength ( functional fibrinogen MA ) , showing that deterioration towards hypocoagulability in any TEG variable significantly increased the risk of death .
