01 · The sentence it was drawn from

“Four studies (64 rodents) investigating adipokines (leptin and adiponectin) showed significant differences following CP supplementation for adiponectin (increased, p < 0.01; SMD = 1.04; CI = 0.47, 1.6) and leptin (decreased, p = 0.01; SMD = −1.33; CI = −2.36, −0.31; both Fig. 4B, C, respectively).”
