  1. Only GP-involved patients were included in the analyses. Adjusted and unadjusted associations for long intervals (4th quartile) are presented as prevalence ratios (PRs) with 95% confidence intervals (95% CI).
  2. 1Years of education. 2Index date: day before first contact to GP.
  3. Effect of gender, age, education, comorbidity and marital status are mutually adjusted. GP’s symptom interpretation and use of fast-track are adjusted for gender, age, education, comorbidity and marital status.
