In the original article, under the abstract and result section: Osteoporosis frequency in RA patients (mean age 63 years, 75% female) decreased from 20% in 2007 to 6% in 2017 (p < 0.001). The values given are incorrect.

In both sentences, 6% needs to be replaced by 15%, this corresponds to the correct information in Table 3.

The authors have overlooked the errors during proof corrections stage.
