2. Fig. 1
Age- and gender-adjusted rates of dysvascular amputations, by race, standardized to the 1986 Maryland population. P values indicating significant differences: racial differences in rates, P<.001; increase in amputation rates among black persons over time, P=.004; increase in amputation rates among nonblack persons over time, P<.001. No statistically significant changes existed in the racial gap (black–nonblack differences) over time.

Age- and gender-adjusted rates of toe amputations, by race, standardized to the 1986 Maryland population. P values indicating significant differences: racial differences in rates, P<.001; increase in amputation rates among black persons over time, P=.016; increase in amputation rates among nonblack persons over time, P<.001. No statistically significant changes existed in the racial gap (black–nonblack differences) over time.

Age- and gender-adjusted rates of foot amputations, by race, standardized to the 1986 Maryland population. P values indicating significant differences: racial differences in rates, P<.001; increase in amputation rates among black persons over time, P<.001; increase in amputation rates among nonblack persons over time, P<.001; widening disparities by race (black–nonblack differences) over time, P=.004.

5. Fig. 4
Age- and gender-adjusted rates of transtibial amputations, by race, standardized to the 1986 Maryland population. P values indicating significant differences: racial differences in rates, P<.001; increase in amputation rates among black persons over time, P=.016; increase in amputation rates among nonblack persons over time, P=.042. Widening disparities by race (black–nonblack differences) over time approached but did not reach statistical significance (P=.11).

6. Fig. 5
Age- and gender-adjusted rates of transfemoral amputations, by race, standardized to the 1986 Maryland population. Racial differences in rates are significant at the P<.001 level. No statistically significant time trends existed in amputation rates among black persons, amputation rates among nonblack persons, or in the racial gap (black–nonblack differences) over time.
