Figure 2. — The effect of psyllium fiber on body weight (A), BMI (B), and waist circumference (C) in overweight and obese individuals relative to negative control. Squares represent the mean treatment difference with 95% CI. Diamonds represent the overall effect size and 95% CI, using the generic inverse-variance random-effects model. As mentioned earlier, the sign of the Pal et al. (2011) result shown here for waist circumference is opposite that reported in the publication; this corrects an error found through correspondence with the first author. CI = confidence interval; BMI = body mass index.
