Fig 2. Forest plot of MDI scores in the long chain polyunsaturated fatty acid supplementation groups vs. controls; standardized mean differences with 95% confidence intervals and weight percentage are shown.

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).
