Methods and materials
We conducted a retrospective review of all mammograms performed from January 2016 to August 2018 at King Abdullah II University Hospital. Each case consisted of a standard two-view mammograms of both breasts. Mammograms were obtained using digital mammography unit.
Mammographic breast density was defined according to the American College of Radiology Breast Imaging Reporting and Data System (ACR-BIRADS 5th version) as follows: ACR-BIRADS (a) the breasts are almost entirely fatty; (b) there are scattered areas of fibroglandular density; (c) the breasts are heterogeneously dense, (d) the breasts are extremely dense. All mammograms were classified to specific mammographic breast density by three expert radiologists. If mammographic breast density classification was different, the majority rating (two of three readers) was used.
Descriptive analyses were used to examine the association between age and breast density. Kurskal-Wallis and Spearman’s test were conducted to evaluate the correlation between age and breast density. P value of less than or equal to 0.05 was set as the threshold for significance.
