2. FIGURE 1
Total protein concentration (A) and superoxide dismutase activity (B) samples of FF (n = 114) and serum (n = 28). The boxes represent the 25th–75th percentile points of the data; also shown are the 50th percentile (horizontal line) and the mean (dashed line). Bars represent the 10th and 90th percentiles and circles represent the 5th and 95th percentiles. ∗P<.001, determined by Student’s t test. †P<.001, determined by Mann-Whitney U test.

3. FIGURE 2
Correlation between superoxide dismutase activity in FF and serum. Each point represents a single follicle’s superoxide dismutase activity and the corresponding serum activity from an individual patient. The 95% confidence intervals are shown above and beneath the regression line (r = 0.552; P<.0001; 95% confidence interval, 0.40–0.67 by Spearman’s rank correlation analysis).

4. FIGURE 3
Correlation between protein concentrations in FF and serum. Each point represents a single follicle’s total protein concentration and the corresponding serum concentration from an individual patient. The 95% confidence intervals are shown above and beneath the regression line (r = 0.346; P<.0002; 95% confidence interval, 0.17–0.50 by Pearson’s correlation analysis).
