In these models, age and experience of care indices are continuous variables.
2For the Cox regression regarding first symptoms-to-investigation time, the origin of the time-scale of the analysis was the date of first symptoms and the exit point was the start of investigation. For the analysis of investigation-to-diagnosis time, the origin of the time-scale of the analysis was the start of the investigation and the exit point was the disclosure of the diagnosis. A hazard ratio greater than one indicates a shorter time, that is, that the event (investigation, for the symptoms-to-investigation time, and diagnosis, for the investigation-to-diagnosis time) occurred more rapidly.
Note: results were similar for models including level of morbidity or type of PHC clinic as covariates, for models excluding symptom urgency, and for analyses performed for the subgroup of patients who had used their usual source of PHC as point of entry into cancer investigation.
