Association of DTD time on a continuous scale and the risk of POF by restricted cubic spline. The red solid line represents the log OR, and the red shaded area represents the 95% confidence interval. The model was adjusted for alcohol abuse, hospital transfer, time from onset to diagnosis, and SOFA and Apache II scores on admission. CI confidence interval, DTD from diagnosis to completion of one DFPP session, OR odds ratio, POF persistent organ failure.
