Monthly change in breast screening and diagnostic procedures after the onset of the COVID‐19 pandemic. The predicted mean numbers of examinations for (A) all mammograms, (B) screening mammograms, (C) diagnostic mammograms, and (D) breast biopsies conducted among participants at a subset of Carolina Mammography Registry imaging facilities were estimated using interrupted time series models. For each month after the onset of the pandemic (through September 30, 2020), the percentage change estimate compares the observed predicted mean with the expected predicted mean. Vertical lines within the histogram bars denote the 95% CIs for each estimated proportion.
