- Figure 1. Inclusion and exclusion of people to the cohort with long-term conditions. CKD = chronic kidney disease. UTS = up to standard (GP practice data quality).
- Figure 2. Venn diagram for numbers with each of the three long-term conditions and the overlap between them (933 907 individuals). CKD = chronic kidney disease
- Figure 3. Tests ordered per person per year for people with only hypertension (left), only type 2 diabetes (middle), or only chronic kidney disease (right). Note: Box plot shows median, interquartile range (25th and 75th percentiles), and whiskers are 10th and 90th percentiles.
