Figure 1

Distribution of the risk score from the existing time-dependent survival model and the trend indicators over time. The graphs above show the value of the risk score from the existing time-dependent survival model (Figure 1A) and the five trend indicators (Figure 1B-1F) at the 5th, 25th, 50th, 75th, and 95th percentile of observed values on each of the first 14 days of admission. The value of each trend indicator is positive or negative for an increase or decrease in the risk score, respectively. TD = number of consecutive days with a trend in the risk score; AC-PD = absolute change in the risk score from the previous day; AC-ST = absolute change in the risk score from the start of the trend; RC-PD = relative percent change in the risk score from the previous day; RC-ST = relative percent change in the risk score from the start of the trend.
