From: Benefits of the microalgae Spirulina and Schizochytrium in fish nutrition: a meta-analysis
Forest plot summarizing the effect of Schizochytrium replacement on the omega-3 fillet content of farmed finfish. Each trial (n = 43) is represented by a square whose size is proportional to its relative weight, its width represents the 95% CI, the horizontal line the 99% CI, and the center the Standardized Mean Difference (SMD) corrected for small sample size (Hedge’s g). The grey diamond at the bottom represents the overall effect extending over the 95% CI. The solid vertical line denotes the zero effect, and the dotted vertical line the SMD under a random effects model.
