Significant treatment effects were observed, parathyroid hormone levels were significantly decreased when compared to the baseline. Anti-inflammatory cytokine IL-10 was significantly higher in the intervention group at 9 months and pro-inflammatory cytokine TNF-a was increased in controls but remain constant in the therapy group.

The gene discussed is PTH; the disease is congestive heart failure.
