From: Prevalence of low central venous oxygen saturation in the first hours of intensive care unit admission and associated mortality in septic shock patients: a prospective multicentre study

Figure 3

Survival curve and death rate (%) at day 28 according to initial lactate level and central venous oxygen saturation (S cv O 2 ). The left part of the figure shows survival curves in four patients’ subgroups according to their initial zero hours (H0) lactate concentration and ScvO2. The right part of the figure shows the day-28 death rate in each subgroup. Numbers inside the bars are number of non survivors/total number of patients in each subgroup. aUnadjusted pair comparison of survival curves between the different subgroups were not statistically significant on log-rank test. bThere was no significant difference in crude death rate at day-28 among the four groups (chi-squared test). However, there was a significant global trend towards higher death rate from the condition with normal lactate and ScvO2 to the condition with high lactate and low ScvO2 (P <0.001, Cochran-Armitage test).
