My question is if eGFR did not increase in the treated group why would DM have been asked by Kamyar Kalantar Zadeh to withhold that data until the NKF conference 6 months later ,  I would imagine if the data was not good no point in presenting but rather just release  it at the AHA and be done with it.  Unless Kamyar Zadeh is enthrilled to do a late breaking abstract on this data...
