Fig 8. Forest plot of the PDI scores by testing age for the long chain polyunsaturated fatty acid supplementation groups vs. the controls; standardized mean differences with the 95% confidence interval and weight percentage are shown.

Subtotals are for the testing age less than 12 mo and 13 mo-24 mo. Fish/fungal oil: long chain polyunsaturated fatty acids from fish/fungal oil. Egg/fish oil: long chain polyunsaturated fatty acids from egg-derived triglyceride/fish oil. LCP1: supplements of evening primrose oil (18:3ω6 0.32 mol/100 mol) and a single dose of purified fish oil (LCPω-3 0.38 mol/100 mol). LCP2: supplements of evening primrose oil (18:3ω6 0.32 mol/100 mol) and a double dose of purified fish oil (LCPω-3 0.8 mol/100 mol).
