A 2001 study by Peter Markewell (BSc, BVetMed, MRCVS) for the Waltham Centre for Pet Nutrition found that "...using a phosphate- and protein-restricted diet, in combination with oral phosphorus-binding agents in those cats in which control of hyperphosphatemia [high phosphorus] and RHPTH [renal secondary hyperparathyroidism] was not achieved by diet alone, resulted in more than doubling of average survival time from the commencement of treatment."
