2. FIGURE 1
The ability to visualize anterior abdominal wall structures as a function of body mass index (BMI). Superficial epigastric vessels were visualized by transillumination, and the inferior epigastric vessels and bladder by direct visualization. Solid bars represent normal weight (BMI <25 kg/m2), open bars represent overweight (BMI = 25–30 kg/m2), and hatched bars represent obese (BMI >30 kg/m2) patients.

3. FIGURE 2
The relationship of the relative location of the superficial epigastric (SE) and inferior epigastric (IE) vessels to body mass index (BMI). Each point is the average distance of the SE lateral to the IE (n = 120). The bold line is a plot of the linear regression of these two measurements.
