Fig. 3From: Impact of acyclovir use on survival of patients with ventilator-associated pneumonia and high load herpes simplex virus replicationa–c Hazard ratios for ICU death from the adjusted multivariable Cox model: the multivariable Cox model was adjusted for age, sex, and SOFA score at d0. The hazard ratios are labeled on the x-axis. The horizontal bars are 95% confidence intervals (95% CI), and significant (< 0.05) p values are indicated with asterisk. a Entire cohort. b Subgroup with low viral load (103–105 HSV copies/mL). c Subgroup with high viral load (> 105 HSV copies/mL)Back to article page
