Fig. 2From: Detection and treatment of omega-3 fatty acid deficiency in psychiatric practice: Rationale and implementation a The percentage of subjects residing in the U.S. (n = 27,426) and psychiatric patients admitted to the inpatient clinic at The Lindner Center of HOPE (n = 131) with an ‘omega-3 index’ (whole blood EPA + DHA) of ≤4.0 % of total fatty acid composition. b Histogram comparing ‘omega-3 index’ (EPA + DHA) frequency distribution of the psychiatric patient sample to the OmegaQuant reference sample. Note that the majority (75 %) of psychiatric patients exhibit whole blood EPA + DHA levels at ≤4 percent of total fatty acid composition, a rate that is significantly greater than general U.S. population norms (25 %, ***P ≤ 0.0001, Chi-Square)Back to article page
