Chloride, mmol/d	105.6±2.0	104.7±1.5	96.5±2.5a,b	99.0±1.4
Bicarbonate, mmol/d	25.4±0.9	28.8±0.7	27.5±1.0	28.9±0.7
Ca, mg/dl	10.2±0.2	10.4±0.2	10.0±0.4	10.8±0.3
Phosphate, mg/dl	5.47±0.17	6.33±0.27	5.90±0.38	6.54±0.41
Creatinine, mg/d	0.30±0.03	0.29±0.01	0.25±0.01	0.27±0.01
PTH, pg/ml	612.2±179.4	669.4±180.9	168.7±22.8	350.7±64.5
RANKL, pg/ml	31.1±7.0	45.1±9.6	61.1±16.0	102.1±27.9a

Results are mean±SEM for nine to ten rats per group. There were no significant differences comparing KCl+CTD to KCit+CTD. KCl, potassium chloride; PTH, parathyroid hormone; RANKL, Receptor activator of NF-κB ligand.

^aP<0.05 versus KCl alone

^bP<0.05 versus KCit alone.
