Results of apixaban concentrations within the first 3.5 days after admission in patients without early re-exposure to apixaban. Patients reaching the 30-day in-hospital mortality are marked by red lines. Thick lines show the line corresponding to the exponential decay from a model that includes the effects and interactions of the treatment groups. Vertical axes are scaled logarithmically. Patients with major bleeding: n = 38, 113 apixaban concentration measurements; Patients with urgent surgery: n = 22, 108 apixaban concentration measurements.
