Treatments effects on psychological variables (mean scores) by presence/absence of clinical levels of symptoms at baseline (see Data 
depression
No significant group, time, or interaction effect was observed on PHQ‐9 and FACT‐Cog scores as a function of the presence/absence of clinical levels at baseline. HADS‐D scores significantly improved over time in patients with clinically meaningful depression at baseline, but not in patients without a clinical level of depression. However, there was no difference in whether patients had received MAG‐EPA or placebo. For HADS‐A, FCRI, ISI, and FSI, a significant change over time was found both in those with a clinical level and those with a nonclinical level at baseline. Again, there was no difference between MAG‐EPA and placebo groups.
