4. FIGURE 3
Mean (±SE) of basal insulin levels after glucose load in healthy controls (open bar) and in seven women with PCOS and insulin resistance (G:I <4.5; shaded bar). Women with PCOS were studied before and during naltrexone treatment. Values are expressed as area under the curve (insulin AUC). ∗P<.05 patients with PCOS during treatment vs. baseline values. ∗∗P<.001 controls vs. patients with PCOS at baseline.
