**3.10 Radiological evidence of ROD**

Of the patient that had symptoms of ROD, 5 (71%) had bone pain while 2 (29%) had pruritus. Only 1 (20%) of the 5 patients that had bone pain showed radiological evidence of Rugger-Jersey spine (see appendix 1), constituting 9%of the CRF group. Table 10 shows the
