Role of intermediate lactate values in patients with severe sepsis and septic shock. An important increase in the risk of death can be observed from the 2 mmol/L value in both groups, although patients with septic shock exhibit a higher risk of death. The risk of death was adjusted by a nonlinear locally weighted function called Locally Weighted Scatterplot Smoothing (LOESS). The gray area corresponds to a confidence interval of 95%.
