Simplified Markov model representation. Patients start the Markov process in the ‘Alive’ state, where they can remain or move to the ‘Symptomatic UTI’ or ‘Haematuria’ states. These are considered sub-states of the ‘Alive’ state since they last less than 1 year. The model accounts for the possibility of patients dying from causes other than UTI (death of other causes). HC, hydrophilic coated catheters; pt, patient; UC, uncoated catheters; UTI, urinary tract infection.
