Figure 1From: Age-related changes in Serum Growth Hormone, Insulin-like Growth Factor-1 and Somatostatin in System Lupus ErythematosusLinear regression analysis. Serum growth hormone levels (Panel A) or serum IGF-1 levels (Panel B) were plotted as a function of age in a normal female subject group. The results indicated that while serum growth hormone levels were not correlated with age (adjusted r2 = 3.03), IGF-1 levels were inversely correlated to age (r2 = 0.269).Back to article page
