Trends in SSD-related healthcare visits in the 365 days before index coccidioidomycosis diagnosis in study of frequency and duration of diagnostic delays associated with coccidioidomycosis and risk factors for missed diagnoses, United States. A) Raw SSD visit counts for each day before the index coccidioidomycosis diagnosis. B) Expected trendline (in red) estimated from visits between 92–365 days before the index coccidioidomycosis diagnosis; vertical blue line indicates start of the diagnostic opportunity window, beginning 91 days before the index diagnosis. Estimated number of missed diagnostic opportunities is depicted as the area between the observed line (in black) and the expected trend (in red) during the diagnostic opportunity window (region to the right of the blue line). SSD, symptomatically similar diagnosis.
