2. FIGURE 1
Interleukin-18 (IL-18) levels in serum, peritoneal, and pleural fluids during the acute phase of OHSS (red colors) as compared to serum of IVF patients not developing OHSS (control group 2) and of healthy controls (control group 1) (green). Values are presented as mean ± SE. Asterisks indicate statistically significant differences, as compared with both control groups (P<.05).

3. FIGURE 2
Serum interleukin-18 (IL-18) levels during the acute (red), convalescence (blue), and resolution (green) phases of OHSS. Values are presented as mean ± SE. Asterisks indicate statistically significant differences between the acute and both convalescence and resolution phases (P<.05).

Serum interleukin 6 (IL-6) levels during the acute (red), convalescence (blue), and resolution (green) phases of OHSS. Values are presented as mean ± SE. Asterisks indicate statistically significant differences (P<.05).

Changes in clinical parameters of OHSS during the acute, convalescence, and resolution phases. Hematocrit (HCT) = green line, white blood cell count (WBC × 103) = red line, serum estradiol levels (E2 × 103) = blue line.
