We analyzed cortical porosity (Ct.Po) in patients on hemodialysis enrolled in a previous randomized clinical trial.
Ct.Po was already high at baseline in the majority of patients and correlated with PTH levels, despite turnover status.
Ct.Po increased after one-year in most patients, and neither gender nor any choice of therapy has affected Ct.Po increase.
The increase in Ct.Po was significant only in non-white patients and correlated with the delta of PTH.
