Randomized Controlled Trial Comparative Study Clinical Trial
Mortality rates and risk factors for coronary disease in black as compared with white men and women.
Currently recognized risk factors for coronary artery disease have been identified primarily from investigations of white populations. In this investigation, we estimated mortality rates for coronary disease and for any cause and identified risk factors for death from coronary disease among whites and blacks. ⋯ Although the rates of death from coronary disease were somewhat lower among black men than white men and higher among black women than white women, the black:white mortality rate ratios were not statistically significant, and the major risk factors for mortality from coronary disease were similar in blacks and whites in the 30-year follow-up of the Charleston Heart Study.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of dietary supplementation with very-long-chain n-3 fatty acids in patients with psoriasis.
In several studies dietary fish oil has been found to have beneficial effect on psoriasis, but the results are contradictory and based mainly on open studies or studies of small numbers of patients. ⋯ Dietary supplementation with very-long-chain n-3 fatty acids was no better than corn-oil supplementation in treating psoriasis. Clinical improvement was not correlated with an increase in the concentration of n-3 fatty acids in serum phospholipids among the patients in the fish-oil group, whereas there was a significant correlation between clinical improvement and an increase in eicosapentaenoic acid and total n-3 fatty acids in the corn-oil group.
