Fig. 2

Intersection diagram with patterns of co-occurrence of diseases within single individuals. The diagram visualises co-occurrence of diseases as a matrix in which the rows represent the individual diseases and the columns represent their intersections, i.e. the different combinations of co-occurring diseases. All diseases that are part of a given combination are shown as black dots connected with a vertical black line (if a disease is not part of the combination a grey dot is shown.) The number of participants with a given combination of diseases is shown as a vertical bar on top of the matrix, the number of participants with any one disease is shown as a horizontal bar to the left of the matrix. Online version of the figure allows users to select particular combinations of diseases, involving any specific disease and includes separate plots for men and women https://www.ergo-onderzoek.nl/multimorbidity-velek-etal
