Kaplan-Meier product limit estimates of diagnostic delay. The plot shows the relationship between the cumulative proportion of patients without bipolar disorder diagnosis and the time past after entering the specialist mental healthcare system for the first time. Patients with zero diagnostic delay are responsible for the vertical line at the beginning of the survival function. The structural break in the curve at 11 years can be explained by the availability of electronic records; patients being diagnosed with bipolar disorder early 2015 might have a delay of 11 years as maximum, while patients being diagnosed with bipolar disorder late 2016 might have a delay of 13 years as a maximum
