Overview of selected length two and three trajectories ordered by age at diagnoses. A Plot illustrating the mean age at diagnoses D1 and D2 for the 25 directional diagnosis pairs that most patients followed arranged by mean age at D1 (in descending order going down on Y-axis). Each horizontal line segment corresponds to a length two trajectory. B Plot illustrating the mean age at diagnoses D1, D2, and D3 for the 25 length three trajectories followed by most patients where fitted age at D1 is between 65 and 70 years and who weren't disease by the end of the study (absence of Y99). X-axis: Age in years (continuous). Y-axis: Length two (A) or three (B) trajectories. ICD-10: International Statistical Classification of Disease and Health Related Problems 10th Revision. Color key according to ICD-10 chapter and available in Additional file 1: Figure S3. Circles indicate diagnoses. Diagnosis D1 is a diagnosis that appears at the earliest age and will be represented furthest to the left. For a full list of ICD-10 code definitions see Additional file 1: Table S1
