Superoxide dismutase activity in human follicular fluid after controlled ovarian hyperstimulation in women undergoing in vitro fertilization  Luca Sabatini, M.D., Claire Wilson, B.Sc., Adrian Lower, Talha Al-Shawaf, M.D., J.Gedis Grudzinskas, M.D.  Fertility and Sterility  Volume 72, Issue 6, Pages 1027-1034 (December 1999) DOI: 10.1016/S0015-0282(99)00411-2

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. Sabatini.

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). Sabatini.

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). Sabatini.
