Estimated proportion of hysterectomies that are subtotal. *A small Los-Angeles study [16] reported a declining proportion of subtotal hysterectomies from 100% in 1940, to 64% of procedures between 1940–1949, 39% of procedures over 1950–1959 and dropping to 5% in 1975. @ NIS data was used to inform hysterectomy procedures from 1992–1995 [30]. ** NHDS data was used to directly inform the proportion of hysterectomies that are subtotal for the years 1997–2009 with data obtained from publicly available datasets [27] reported for each year-of-age from 15 to 99 and for each individual year. ^ Data from the NIS was used to inform the proportion of hysterectomies that are subtotal from 2009 to 2013. The proportion of hysterectomies that are subtotal during 1990–1993 was based on NIS data.
