125 Cardiac surgery in Influenza-Like-Illness season 6 Figure 1. Relationship between influenza-like illness prevalence (per 100,000 persons, left Y axis, in light gray) and duration of mechanical ventilation (in hours, right Y axis, black line) between beginning of 2014 and beginning of 2020. Epidemic threshold, which changed in 2019, is drawn in red Figure 2. Results of Cox regression analysis showing hazard ratio of stopping invasive mechanical ventilation (IMV) in influenzalike illness (ILI) season compared with baseline season for different years. Influenzalike illness season, year of surgery, age, sex, body mass index, Acute Physiology and Chronic Health Evaluation IV predicted mortality, type of surgery, Charlson comorbidity index, Age, Creatinine, and Ejection Fraction II risk score, hospital type, and intensive care unit occupancy rate were included as predictor variables
