After 14 months, (a) circulating phosphorus was higher in the LPD alone group, while circulating PTH was lower in the LPD + keto-analogues group, and (b) in the LPD + keto-analogues group, circulating FGF23 was lower, while circulating Klotho was higher versus the LPD alone group. Here, FGF23 is linked to disseminated peritoneal leiomyomatosis.
