Fig. 7From: A comprehensive framework to estimate the frequency, duration, and risk factors for diagnostic delays using bootstrapping-based simulation methodsCounts of SSD visits each day prior to the index diagnosis. For each disease of interest there is an upward spike in the occurrence of healthcare visits with SSDs in the period just preceding the index diagnosis. The black vertical line represents the estimated change-point separating the diagnostic opportunity window from the prior crossover period. The red line represents the expected level of healthcare utilization (i.e., estimated to occur in absence of diagnostic delays)Back to article page
