Figure 3From: Nebulized heparin is associated with fewer days of mechanical ventilation in critically ill patients: a randomized controlled trialRate of freedom from mechanical ventilation. Over the first 28 days among surviving patients, the rate of freedom from mechanical ventilation was higher in patients administered heparin. Median times of ventilation were 5 days in the heparin group (n = 20) and 8 days in the placebo group (n = 21) (P = 0.01) (log-rank test).Back to article page
