Figure 4. Daily CUSUM scores for albumin.
The daily CUSUM score for Alb was calculated for either good Alb (Panel A and B) or bad (10% high bias) Alb test results (Panel C and D) for the simple (Panel A and C) and full CSLR model (Panel B and D). Dark points show CUSUM scores that exceed the cutpoint for error detection. Central line shows mean Cusum score versus test count. (n=1093 days)
