Baseline – 9 months prior to consenting
Time point 1 - NO CME: 0-9 months after consent, CME/EARLY: 0-9 months after completion, CME/LATE: 0-9 months after consent
Time point 2 - NO CME: 9-18 months after consent, CME/EARLY: 9-18 months after completion, CME/LATE: 0-9 months after completion
adjusting for mammography registry and radiologist random effect
mammogram-level variables: mammography registry, age group at time of mammogram, use of HRT, time since last mammogram, history of prior breast procedure; also adjusting for radiologist random effect
radiologist-level variables: academic affiliation, yrs of interpretation, percent of time in breast imaging, percent of mammograms that are screening; also adjusting for radiologist random effect. Models exclude radiologists missing radiologist survey
