Abstract
The study was carried out to compare the 10-yr risk of major osteoporotic fracture provided by the tool of Osteoporosis Canada (OC) and by the WHO’s calculator FRAX on an identical group of postmenopausal women. We randomly selected n.298 women aged 50 yr and older ,we collected the risk factors requested by the algorithms and we performed DXA scan.Then we calculated the risks . The mean age of our sample was 60,05 yr (range 50-84).As expected, the differences in the rate of women’s assignment to analogue risk classes by the two tools were statistically significant (p<0,001). The rate of accordance, in terms of class risk allocation, was of 41,9%, in all other cases FRAX indicated lower risk classes than the OC’s tool and in 9,7% they respectively assigned a low risk vs an high risk for identical womenI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
